This guy is just unbelievable! In his video he talks about how he took a simple mouse apart and used the rollers on a hand device. He then borrowed another mouse from his friend and had four rollers on it for each finger. He later perfected it to finger devises for both hands. He shows how he can write sticky notes and transfer them to the computer. Now he has a shifting paper for a laptop. This is very cool, because he puts software on any piece of paper and can then transfer it to a computer. Amazingly this is going to be open source software next month.
