Probably the only advertisment on my site: bokus.com, the famous Swedish web book store, of which I once (as a consultant) was senior developer, programmer, sometimes project manager, and now my employer. Some of my early book purchases. (Links to bokus.)

This is a link to Svenska Tai Chi Chuan Institutet, founded by Klas Larsson, my teacher in Tai Chi Chuan/Taijiquan. Text mostly in Swedish.

And later in this sentence is a link to the site of Magnus Bodin: x42.com. He has done a lot of fun stuff.
