buddha.jpg ... (JPEG, 405 by 540 pixels, 84 KBytes)

A buddha statue in Wat Arun, Bangkok. This was in a courtyard with similar Buddha statues in the cloisters on all four sides.

I took this photograph in December 2003, with a Canon S400 digital camera. The full resolution version (cropped) is in the photos section of this web site, together with more photographs from that trip.

cuillinCauldron.jpg ... (JPEG, 810 by 540 pixels, 93 KBytes)

The Cuillin ridge on Skye, looking south from just below Sgurr nan Gillean, at the point where the "tourist route" meets the ridge (about 800 m.)

I took this photo in June 1998, while hiking with Eleanor (age 10 at the time). As you can see, there was mist swirling out of the next corrie along from us, although the path we were on remained clear.

eAtRidge.jpg ... (JPEG, 810 by 540 pixels, 114 KBytes)

This photograph is taken from the Cuillin ridge on Skye, looking south-west from just below Sgurr nan Gillean, at the point where the "tourist route" meets the ridge (about 800 m.). The first dip (just below Eleanor) is Harta Corrie, and beyond that is Coruisk, with the western arm of the Cuillin ridge forming the skyline in the background.

I took this photo in June 1998, while hiking with Eleanor (age 10 at the time).

hal.jpg ... (JPEG, 405 by 540 pixels, 47 KBytes)

This is a sketch for the costume design for Prince Hal (played by Dan Donohue) in Henry IV Part 1 at the Oregon Shakespeare Festival in 1997.

This was scanned from the original drawing. It is subject to my copyright, although the actual costume design might well have more restrictive copyright attached to it.

heriots5.jpg ... (JPEG, 803 by 540 pixels, 131 KBytes)

A view of the quadrangle in George Heriot's School, Edinburgh. The building was started in 1628 and it opened as a school in 1659 (after a delay caused by being occupied by Oliver Cromwell; the building still has marks from a canonball that was fired on it from Edinburgh Castle, which didn't support Cromwell at the time.) For more information, see the school's web site.

I was educated at Heriot's from 1959 to 1969.

This is plate V from "Historical and Descriptive Account of George Heriot's Hospital", published by Cunningham and Johnstone in Edinburgh, 1827. The original is undoubtedly out of copyright. I scanned this from my copy of the book.

kells.jpg ... (JPEG, 416 by 540 pixels, 86 KBytes)

This is folio 292r from the Book of Kells. It is the start of St John's gospel, and it consists purely of the words "In principio erat verbum" (In the beginning was the word). The Book of Kells is an illustrated manuscript of the four gospels, created around 800 A.D. (probably in Kells, Ireland or on Iona, an island off the West coast of Scotland). The word "illustrated" is an understatement - it is probably the finest illustrated codex still in existence, and perhaps the finest ever. Almost every page has intricate colored illustrations, and the major pages such as this one are completely decorated. This scan, which has a resolution of roughly 40 pixels per inch, can't come close to showing the details of the illustration.

The Book of Kells is in the library of Trinity College, Dublin. There are several publications available with much better reproductions than my one; I recommend "The Book of Kells" by Bernard Meehan (ISBN 0-500-27790-7) available for about US$20. There's a also comprehensive CD-ROM of the Book of Kells. At the more expensive end of the spectrum, you can buy a facsimile version from Fine Art Facsimile Publishers of Switzerland (Lucerne), for around US$18000.

king.jpg ... (JPEG, 324 by 540 pixels, 35 KBytes)

This is a king from the Lewis chessmen. The pieces were discovered on the Isle of Lewis in Scotland in 1831. The discovery consisted of 93 carved pieces; 78 of them were chessmen. They are carved from walrus ivory, and are generally believed to have been created in Scandinavia about 1050. Most of them are now in the British Museum, though some are in the National Museum of Antiquities in Edinburgh.

The British Museum publishes a pamphlet by Michael Taylor with some details about the chessmen (ISBN 0-7141-1347-6). There's also a more humorous account of the travails of the pieces written by Irving Finkel (ISBN 0-714100573-2). Both seem to be out of print at the moment.

There are numerous replicas of the pieces available: try the usual search engines.

This is a photo of a model of one of the kings. The background of the full size image is the result of me playing with Adobe Photoshop. The photo is subject to my copyright.

knot.gif ... (GIF, 370 by 185 pixels, 26 KBytes)

This is a detail from an illuminated manuscript in the British Museum, taken from plate 64 of the Grammar of Ornament. It's a good example of the knotwork decoration typical of Celtic design in the fifth through tenth centuries A.D. As is frequently the case, this knot is woven from a single thread.

Click on the image to view an animation showing the knot being woven.

The Grammar of Ornament is a wonderful book by Owen Jones, first published in 1856. It includes a wide range of samples of abstract decoration from around the world and through the centuries. The original folio edition is now a collectors' piece, costing thousands of dollars. Fortunately, there are reprints available. On paper, you can find it at Amazon.com. There's also a very nice CD-ROM edition available from Direct Imagination

scotia.jpg ... (JPEG, 720 by 540 pixels, 110 KBytes)

This is the map of Scotland from "Theatrum Orbis Terrarum", 1575 edition (with Latin text), by Abraham Ortelius. The Theatrum is generally considered to be the first "atlas" in the modern sense of that word. See for example the description at the Library of Congress. Note that in this map Ortelius chose to draw North to the right. (This is different from the surveying errors that gave Scotland a peculiar shape in the earlier Ptolemaic maps of Britain).

The original is (of course) out of copyright, and this image is public domain. I have higher resolution versions too - send me email if you have a good use for them.

selket.jpg ... (JPEG, 387 by 540 pixels, 40 KBytes)

This is a detail from a figurine of the Egyptian goddess Selket. It came from the tomb of Tutankhamun, where it was one of four goddesses guarding the canopic chest. It's made of gilded wood. Selket was associated with scorpions, and with helping in childbirth and healing.

I scanned this from an exhibition catalog. I also have a photo of the entire figurine (JPEG, 413 by 540 pixels, 27 KBytes). The original figurine has been out of copyright for about 3300 years.

sgurr_nan_gillean.jpg ... (JPEG, 810 by 540 pixels, 71 KBytes)

This is a view of the Cuillin mountains on the Isle of Skye, from near Sligachan.

The tallest peak (left) is Sgurr nan Gillean (965 m., 3166 feet), and the tall one on the right is Sgurr a Bhasteir (898 m., closer than the others). Between these are (left to right) Am Basteir (935 m.), the tiny Bhasteir tooth (915 m.), and Sgurr a Fionn' Choire (930 m., further away than the others). The stream is Allt Dearg Beag (probably at about 100 m.).

If you want to see professional photographs of the Cuillin, I recommend "The Cuillin" by Gordon Stainforth.

I took this photograph with a Rollei 35 in 1994, then had it transferred to photo-CD. It is subject to my copyright.

sligachan.jpg ... (JPEG, 810 by 227 pixels, 28 KBytes)

This is a view of the approach to Glen Sligachan (from the North) on the Isle of Skye. To the right is the Black Cuillin and to the left the Red. At the entrance to the glen, just about the center of the picture, is the Sligachan Hotel.

From Sligachan you can walk through the glen to Camasunary (on the coast), or up into the Cuillin. There are several walking routes (no hands) up to the Cuillin ridge, and easy scrambles from there to various summits. All the walks up to the ridge are hard: several miles on rough trails followed by steep 2000 foot ascents.

The trail through the glen offers a side-path that takes you over a low point on the ridge ridge to Loch Coruisk. That loch is very secluded, being totally surrounded by the Black Cuillin (although there is a daily boat trip to Coruisk from Elgol). The loch is named from the "corrie of water" at its head, which receives a high percentage of the run-off from the Cuillin. The view anywhere around Loch Coruisk is spectacular. But it's a rough path, and it feels much longer than the map would have you believe (14 miles round-trip). And it's always wet.

This is a panorama constructed from three photographs that I took with a Rollei 35 camera in 1994, and transferred to photo-CD. I pasted them together in Photoshop, applying a fair amount of color correction and touch-up in the process. It is subject to my copyright.

wheel.jpg ... (JPEG, 720 by 540 pixels, 187 KBytes)

This is my rendering of a Celtic "wheel cross" design. I based the design on a drawing in J. Romilly Allen's "Celtic Art in Pagan and Christian Times", at page 181. The stone that he drew was found in Pen-Arthur, Wales, and is now in St. David's cathedral in Wales. The original stone design was probably created in the ninth or tenth century A.D.

Romilly Allen's drawing has 23 spokes around the perimeter, unevenly distributed (11 on the right and 12 on the left). I chose to use 23 spokes uniformly distributed. When I looked at the original stone (in St. David's, in 2003) I couldn't tell whether it had 23 or 24 spokes. Either the design was in better condition when Romilly Allen saw it (early 1900's), or Romilly just guessed.

Regardless, I prefer the design as shown here: I think the asymmetry of the spokes makes an interesting counterpoint to the otherwise strong symmetry of the pattern. Using 24 spokes would produce four identical quadrants; with 23, none of the quadrants are identical (nor are the octants).

I drew the pattern in Adobe Illustrator (which means that I can produce the image at any resolution), then rendered it in Adobe Photoshop (using lighting effects and a texture).

wiring_codes.gif ... (GIF, 378 by 540 pixels, 17 KBytes)

This drawing shows various color codes used in wiring 8-position modular plugs and jacks, commonly called RJ-45; it's also useful for 6-position wiring (RJ-25, RJ-14 and RJ-11). It's designed to be printed at 2.5 inches high (I have one glued to my cable tester). For the 540 pixel GIF, that corresponds to 216 dpi.

The information in the drawing and in this page come mostly from the Cabling FAQ (section 9). For alternative pictures and a list of common jack types, see Hubbell Premise Wiring. Another good source for cable information is CablingDirectory.com. Use any of these sources, or this one, at your own risk, of course.

I drew this in Adobe Illustrator. You can also download the Illustrator source file (156 KBytes). The drawing is subject to my copyright.

Here's a summary of what the drawing is about, and some additional details:

• T568A and T568B are the most common standards for running digital signals over 4-pair cables (use either of them, but only one). T568A is nominally "preferred", but in practice T568B is much more common. 10-base-T or 100-base-T Ethernet uses pins 1, 2, 3 and 6.
• The configuration labelled "10BT" is used for running twisted pair Ethernet over 2-pair cables.
• "USOC" (Uniform Standard Order Code) is RJ-61, used for 4-pair telephone service in 8-position jacks. For conventional analog telephone lines, in each pair white with a colored stripe is "tip" and the same color with white stripe is "ring". The colors of the six central pins labelled 2-7 in this drawing are also used for pins 1-6 of 6-position USOC jacks (RJ-11 for one pair, RJ-14 for 2 pairs, RJ-25 for 3 pairs).
• The configuration labelled "POTS" is used in older 2-line domestic telephone installations and in modular patch cables for telephone service (generally with a 6-position, 4-conductor jack). Single-line telephone installations use just the center pair.

Note that modular patch cables for telephone service have the wires at one end reversed (wired in the opposite order). Patch cables for data service are usually wired straight through. A 10-base-T crossover cable has pins (1,2) exchanged with pins (3,6) at one end.

For everything except the POTS configuration, pair 1 is blue, pair 2 is orange, pair 3 is green and pair 4 is brown. For the POTS configuration, the center pair is line 1 and the outer pair is line 2
