Build. I'm calling this the Walking Cannon.
Not the greatest angle for a picture, I know.
The Questions:Can you build something -- a frame, station, or starship -- right away? Yes. (+5)
Is it below, at, or above the golden ratio? Below. (+5)
(The Golden Ratio is $0.10 per part.)
If you can't build a frame right away, or choose not to, does it have parts you should be able to put into use right away? Yes. (+5)
Does it have more than a handful of immediately useful parts? Yes. (+5)
Score: +20 (A+). Another maxed out Mixel.
