Welcome to the Machine...

Being out of milk does not count as a "doomsday scenario."

(Apropos of nothing. I'm just having a Benny & Joon moment. I really should get more sleep.)

Courtesy of the MIT Media Lab, it's a "paintbrush" that samples real world objects (like the eyedropper tool in Photoshop), and lets you paint on a video wall with it.
BTW, it doesn't just sample the color. It also samples texture, and if the object is moving then it captures the motion as an animated sample.

'Ya know what? I can't do it justice by describing it. Check out the kick butt video here! :-)
