Working more on
my animation program, it's capable of stuff like this with dynamic lighting. (Still a wip)

While specifically designed for stick figure animation, you can make a custom figure and assign bitmaps to joints and do a sort of bone animation thing if you'd like. It uses keyframe animation and OpenGL for rendering. Hopefully will be at a stable point sometime this summer.
TISFAT Zero can currently be used for basic animation as it stands, though I still need to work out some bugs with bitmaps and such. I'll provide the most current build to anyone that's interested in playing around with it.
To any of you techy fellows out there: About 60% of the codebase is atrocious and will be redone in the coming months. You have been warned.
