Make improvements to computer vision apps / New computer vision apps

[Marak]

We currently have (4) computer vision based apps / games

https://buddypond.com/app/jutsu <-- cast spells using hand signs https://buddypond.com/app/bubblepop <-- bubble popping game https://buddypond.com/app/stickman <-- real-time stickman / ragdoll movements https://buddypond.com/app/harp <-- vision based musical instrument

These are all super fun to play with and a great starting point to add features or to create new computer vision assisted apps.

Would love to see more contributions to this category of apps; either with improvements to the current set, generalized functionality for gesture recognition, or entirely new apps based on this pattern.

Would a great starting point for new contributors to the project who are interested in computer vision.
