Circuit Playground looks fantastic, and I'd really love to try it out. Unfortunately, I don't own an iPhone or iPad, and can't afford either. Are there any plans to release Circuit Playground on any other platforms? Something that would run on Occidentalis would be ideal. I think that your goal of educating more young people on electrical engineering would be better served if your educational software were more accessible.
