If you've got $500 burning a hole in your pocket and want to be the star of the next MMORGP you play, then grab the AcceleGlove, a glove that lets you use your hand in 3D space to control computer applications. The open source SDK package comes with everything you need to write your own interface and build gesture libraries, so you can go wild and come up with all sorts of cool uses for it.

The AcceleGlove was originally designed to help researchers study hand gestures without building a recognition device for each new project. Now companies are looking at ways to incorporate it into everything from educational sign language products to military equipment for use on the battlefield. The AcceleGlove's software is licensed under the GPL and is free for anyone using it for application development prototyping or research, however an additional license is required for commercial product development.
