Is it just me or does this remind you of Maddie Ziegler in one of Sia's videos? Chandelier video I think. Although how they paused that video well enough to figure out what was written on her hand, I have no idea!
It's a high tech pen. Scan the color you want to use then the pen will draw with that color! I could use for my anime drawings and have the right colors instantaneously. I really want this, drawing would be so much fun with this!
