infernoSand (also known as iSand) is my personal project based off falling sand games. It is a moddable, partially-open source game coded in SDL. The scripting system is built in Lua for simplicity (for me, anyway).
Update (Feb. 9th): I am once again starting on a remake of infernoSand after a loss of all but the very latest build when Linux decided to freak out and delete the personal partition of my external hard drive. Once again, powered by SDL and an in-the-works physics engine called iPhys and scripting with Lua supplemented by the new iLapi (inferno's Lua API). Will support sound and have networking capabilities and be, quite frankly, minimalistic in its source.
Update (Dec. 21st): I am now completely remaking infernoSand! See http://fallingsandgame.com/viewtopic.php?p=158823 for details!
