GPL Edutainment Software

haxot writes "I'm the technologist at a local library. In our lab, I've managed to get some recognition for tools such as GIMP and Open Office, and even such toys as Bomberman and BZFlag. Now I'm turning towards the children's computers, which are mostly filled with ancient, buggy, rather boring games that try to be interactive TV shows rather than something entertaining. I'm looking for good OSS games and education suites (preferably multi-platform — I want to be ready for an OS switch to Linux). I'm not picky about the license; I'd just like the software to actually have that 'neat' appeal. Some examples I've found already are Gcompris and Tux Paint. My focus is the 2-year-old to 8-year-old range, but I'm happy to hear teen-oriented suggestions too. Since it's a public library, however, I can't have any software on the computers that is risqué, gory, or violent."
