WireGoggles displays a real-time wireframe outline of what your camera is pointing at. Choose from 20 color schemes or create your own, and save and share pictures. You can record and play back videos with audio, and export them as WebM files. You can also apply the effects to your existing pictures.
WireGoggles is now open source! See https://github.com/dozingcat/WireGoggles
