apt-get install sun-java5-jdk(and a few other packages) in Debian, as Sun has finally relaxed its license a bit. Note that it's still not free, it's just free enough to be distributed in Debian's non-free section now ;-)
On a related note: I uploaded my Wesnoth game replays (210 KB) for everyone to enjoy. I'm currently playing the Heir To The Throne campaign and finished 16 of 26 levels so far.
For those of you who want to save the money they usually spend in the cinema — grab some beer and watch Wesnoth replays with your friends ;-)
