Phase 1 of my aluminium R2-D2 project took him to a static display level. Recently, I've been motivated to start on phase 2...bringing him to life with electricity.
I'm going for a modular approach that will initially be driven by 12-channel RF remote control, but that will be done through a single power distribution board (which will allow a selection of easily exchangeable power supply options), and 12 centralised relays, so that I can retrofit a number of levels/options of sensor-triggered control later...here's the RC and relay board:

I'll use the 12 channels something like this:
1 rotate dome left (momentary)
2 rotate dome right (momentary)
3 front holoprojector
4 front lights (PSI and logic display)
5 rear lights (PSI and logic display)
6 looped sound effects
7 short sound effects (momentary)
8 short sound effects (momentary)
9 short sound effects (momentary)
10 etc.
11 etc.
12 etc.
