Bin dun... bin dun many times over actually. Check out the badges and challenges sticky at the top for popular jargon for this board. What you're talking about is referred to as "green" solutions. A step further is "brown" where you don't get to use wheels at all. There's some crazy good designs posted though. A few of the regulars on this board are phenomenal designers.
