While going through my Google Reader tonight, I came across this site that caught my attention. After watching the video embedded below, I decided to download the demo and have my 4th grader give it a try. I am personally not very good at this type of thing, but my son loves the challenge. If it is as good as it looks, I may be willing to spend the $19.95 the full version costs. Unfortunately, it requires a PC using Windows Vista or XP. The creator may make a version for the Mac, but he doesn’t make any promises.
