First I worked on the Holoprojectors (they go on his dome) because I thought I had all the parts. Turns out I'm short the curved pieces on the bottom, so the white will need replaced with gray when it arrives. The funny colored plates are just to hold the HP together until it gets on the dome.
In addition to the holoprojectors, I started on the feet. For the main feet I did what I'm calling the "footprint", before it starts angling. For the front center foot I got most of the front and back, and some of the sides done.
