We have a winner (chosen by random.org) for the Leapfrog tag Reading System Giveaway.
It's Fogbythesea, who commented: "I have been looking at these as a way to help my autistic son learn how to read. The pen looks like it may also help with fine motor skills."
I wish I had more to give away, since there was obviously a lot of interest. Thank you to everyone who entered, and I hope to have some other great contests coming up soon.
