Springysim 0.1.0 release
Springysim is an interactive 2-D physics simulation that I wrote in 2000 for a university assignment. I did a bit more work on it in 2003 after I graduated, always intending to make it publicly available. I finally pulled my finger out and got it done. If you do nothing else, wander over to the screen shots page and check out what it can do.
Springysim is wholly useless for any practical activity, but I think most programmers can relate to the flash of inspiration where you think: “Holy Crap! I just have to write a program that does that!”
