Check out the toothy grin on this LEGO bot

Sometimes you see a LEGO part and you think “now what will I ever do with that?” I’ve always loved the greebly, mechanical look of the ripcord housing element, but for the life of me I’ve never found a use for it. That’s not a problem for Cezium, though, who whipped together this brilliant digital model with two whole rows of them for the teeth–er, excuse me, railgun housings on this sentry bot. This just goes to prove that old LEGO building axiom: all pieces are useful if you have a sufficient quantity of them.
