Get Ozobot and accessories here! Seriously, one of the coolest things I have seen in a long time. This does a ton of things and you can watch a great information video explaining it all through the above link. To sum it up though, it is a mini robot that follows lines that you draw either on paper or on a tablet. It will act according to the colors you are using or the patterns you use. I probably just confused you so just click the link and check it out, I can't wait to get one!
