He is using this toy and making the drill move and changing the leds to multi color.
"This piece was actually a lot large than I expected, so I had to do a little redesign in my design rather than chopping of his legs etc. But I like the size! It also allows me to insert machinery inside to make the drill rotate etc.
It has also got built in LED-lights which I intended to do, but this saves me the trouble. It will simply light green when he's active (i.e protecting a little sister), amber/yellow when searching (if a sister is targeted, or a shot is placed at big daddy directly) and finally red - hostile."
