Someone sent this to me a few weeks ago. It has to be the best online game I've played in a LONG time. I got through all the levels, but the fun is going back and either making the simplest possible contraption, or the most complicated.

I had to make myself not play it for a while. I was getting no sleep. <img src="/forums/images/graemlins/zombie.gif" alt="" />

Here are a few of my designs:
Back and Forth
Unpossible
Big Ball

BTW, if anybody has bought the full version, how is it? Are there a ton more levels?
