This is a video picker that gets the color from the pixel that is being pointed by the mouse, and also gets a cropped video of 100×100 pixels, which its center is the mouse.
This is an exercise for understanding how pixels works in openframeworks and how can them be modifyed.
Here you can see a video about the video picker:

These are the resources that I used. They all are from the Openframeworks forum:

The video was done by Chiu Longina for a beat box workshop that he did in Córdoba. The people from the video are some of my mates from the alg-a community. Here you can see the original video: http://www.vimeo.com/293109
