Part 1: Create a program (OpenGL, or DirectX) that creates a series of random 2D objects, (or 3D objects that only move in 2D), about 25 is probably good but you may need more or less and has them move around on the screen, they should wrap around the edges of the screen (both top and bottom). Objects should randomly translate, scale, rotate, and shear (though not all at once generally) and preserve this state as they move around. Don't pick values that are so crazy you can't see any of this happening on screen. Randomly colour them as well. Note: Do this on a black or white background, don't try and handle collisions between objects. In theory it would make sense to use a (very) simply application of the painters algorithm and only draw the top one if there is a collision, but that's not very complicated for this, and doesn't add much.
