Parts. There's a nice blend here, click hinges, mixel joints, cheese slopes, 1x1 round plates, 2x2 turntable, 1x2 hinge brick, etc.
Build. I had the leg idea for this walker bouncing around my head for most of yesterday afternoon. Stats: 2Rh (claws)/2Rd (laser pod)/1Y (sensor pod)/2W
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+). Should we even be surprised at this point? :-)
