It is sad to see that this just turned into a bulldozer competition... so boring.
Rule reminder for you.
Killer Contraption Arena
Build a contraption to push the previous victor off of the battleground.
I'm not necessarily looking for the most effiecient warriors, but interesting battles.
Walkers are encouraged, as well as pretty much anything other than bulldozers.
This is in the interest of keeping the thread moving and not stalemating between subtle tweaks.
