Doesn't sound like this is what you're looking for, but LightBot (http://lightbot.com/) is a wonderful game with similar sounding game play.

Thanks :)

When I was looking for the forgotten game, I crawled through the internet and found almost any other available title (LightBot also). I'm teaching computer science and try to collect as many tools (e.g. games) to people with no programming experience.
