Note:These pages make extensive use of the latest XHTML and CSS Standards. They ought to look great in any standards-compliant modern browser. Unfortunately, they will probably look horrible in older browsers, like Netscape 4.x and IE 4.x. Moreover, many posts use MathML, which is, currently only supported in Mozilla. My best suggestion (and you will thank me when surfing an ever-increasing number of sites on the web which have been crafted to use the new standards) is to upgrade to the latest version of your browser. If that's not possible, consider moving to the Standards-compliant and open-source Mozilla browser.

Merry Christmas! Here are some more presents. I hope these are a bit easier to appreciate than my new paper on infinite-dimensional representations of 2-groups. Again, they’re all about symmetry. But this time you don’t need a math degree to enoy them. You just need to look at ‘em!

They’re pretty pictures of tilings, suitable for use as computer wallpaper. Check ‘em out.

Here’s an example with 5-fold quasisymmetry. It was created by Greg Egan:

Here’s one with 7-fold quasisymmetry, also created by Egan:

You can create your own, too, by going to Egan’s applet webpage and following the instructions there. I did this and tweaked the results a bit to make some that are slightly more dim-hued and mellow, so I can still find the icons on my computer screen.
