I saw this video the other day and have watched it a few times since then. It's really amazing what some people can do with a pen, a sharpie, and some contact solution. It's not until the last bit of the video that it all really comes together and all of a sudden you'll think, "Holy crap!" So make sure you watch it all the way through. This is a great way to get some cool temporary "ink" for the fun of it with no commitment.
