As a part of my Bachelor's Degree work I've developed a soft-body physics library for J2ME. I've optimized it on real-world devices and successfuly released a commercial mobile game using the library - Gish Mobile. Now I thought that it could be useful for other J2ME game developers as well, so I've made it open-source: bloft.hardwire.cz The name is kinda weird, but I couldn't come up with a better one :) The library is written in Java, so it can probably be used for J2SE development as well, but I guess there are more sophisticated J2SE libraries out there.
