I was looking through my referrer logs (absolute, incontrovertible proof of geek lifelessness) when I saw a few hits from a browser (tool, really) called TulipChain. There's a screenshot here. It truly takes so little to amuse me. Requires Java 1.4, which I don't think is installed by default currently on very many operating systems, but then if you're geeky enough to care about playing with something like this then you're also likely capable of finding the right JDK for your machine anyway...
A two-week binge of rest and relaxation so intense that
it takes another 50 weeks of your restrained workaday
life-style to recuperate.
