So now we have Green Machines, Simple Machines, Complex Machines, and (recently) Champions.
The Champions thread got me thinking of what other kind of challenge might be interesting. And it hit me: Speed Demons. The fastest possible solution to any given level.
If you have a fast solution on a level, post it here. If you see one posted here and you think you can make a faster one, then post your faster one. (There's no in-game timer, so close contests will be impossible to call for sure, but we should start seeing some pretty fast machines regardless.) (Actually, an in-game timer would be a nice feature - all it would need to do is show the number of seconds - preferably down to hundreths - between the time the start button is pushed and the time the victory is declared. It wouldn't even need to display during execution - the time could just be displayed in the victory message.)
Anyway, here's my first humble submission:
