"In Time" movie clock
First of all I just saw "In Time" movie, that from Justin Timberlake you know, and I was thinking about the green clock in their arms.
I thought that I can do it with a projector or somekind of stuff like that..( like a PIPBOY 3000 from fallout, projectin right on my arm).
But Imnot happy with that way so Im here asking for help... Would you know how to do a subcutaneous clock or maybe some transparent film around arm with leds, i dont really know. Brainstorming here please!
Note: Sorry for my english, Im not a native english speaker and thanks for your time reading!
