explosions

3D objects flying around resembling explosions with various effects

This is a simplified 3D world with alpha-blended objects that look kind of like fireworks or sparks. It also has a number of effects built in, such as fading, blurring, fire ("heat"), and zooming. It serves no purpose except to look pretty. The source-code is also well-documented, so someone might find it useful in learning SDL routines.
