I assume he's pissed off because he has to live with a stupid name.

This is an in-class assignment today, we were told to spend about an hour making little 1-inch tall marker thumbnails of robots, which was interesting since I've never drawn a robot in my life. So once we'd done about 50 or so (I did 70) of those, then we picked our favourite and did an actual design based on that. Not bad for spur of the moment, honestly, although originally he didn't have a wheel, that was just a lump that he'd pathetically drag around. But it turned out so much better with the wheel and spikes, I made some mods. You can see the original thumb in the corner for scale.

Should do that sort of thing more often, it's fun. In my copious free time, you know.
