Epic Floor Design, although I'm not sure what the idea is. if laid with clear or glass tiles to see the design would be different, but to put black tiles over doesn't make any sense. I wonder if you get a magnifying glass to view the floor.
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.
