Update 25th September 2009: for a very similar picture, see this post by David Eppstein.

[The piece below used to lie around on my homepage since April 2007. I'm slowly closing down that site, as the party is over at Google's Page Creator.]

New Look

I’ve changed the look of my blog. And it now subsumes my homepage. I’ll take that homepage down soon as google page creator seems to be on the verge of going down (or at least, on the verge of being moved to google sites, which doesn’t seem as nice to me).
