In one of my computer graphics courses (Cmput 411), one of the assignments was to implement a program that interactively warped input images. During the course of the assignment (and the others in the course), I became much more proficient with both Java and advanced graphics techniques.

The Java source code is available upon request. I'm not going to give it to anyone looking to cheat, so don't bother asking.

Images created using this program (some were made during development, and may not be reproducible):

Turning the warp up *way* too high
Turn it the other way, and we've got a wormhole
A very nice tall mountain
The original, sadly
Reality distortion field?
Gatesimodo
The original wade
A warped version of Wade
Funhouse mirror Wade
