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!
The RGB Colorspace Atlas designed by American artist Tauba Auerbach. It's a perfect cube, measuring x x and is said to contain every visible colour in existence. Take a look, it's in a book, a Reading Rainbow!
A real life Eyedropper tool! This is awesome. A pen with a little censor that scans the color of the object you point it at, then you can write in ink that exact color, it's like the eyedropper tool in photoshop outside of the computer.
