Programming Lightbot

Today we have done an exercise of educational programming, it was about controlling the nice lightbot: http://lightbot.com/flash.html

My personal opinion: This is a educational program wich you not only learn programming, but  also is very fun. At the beginning it was easy but when you avanced, it was getting more difficult. When you have been doingh it a while, you start to stress you because you can´t make it.
