I have no idea how your supposed to do this one, but the design worked...

Tremendous game. Took me a while to get in get the feel of things, and most of my "fantastic" contraptions look like medival torturing devices. *very* enjoyable, thanks for the link! :D

Thanks for posting this Echolocating, it's very fun and amazingly addictive. Some other people's contraptions are simply ingenious.

you should check out the forums they have some crazy complicated designs in there. I also love creating crazy walking machines and kill dozers.
