This is a fantastic idea and reminds me of how much I learned when asked to complete a "pre-interview" coding test recently. The test covered jQuery, Rails, and Ruby and was quite challenging. For the Rails portion I was giving high-level specs for what the app needed to be able to do, and given an app which had important parts ripped out and a few bugs which had to be fixed just to get it to run. I learned a ton getting the app to run, and then making the app do what it was supposed to. This is a fabulous training/education tool. Nice work and great idea!
