I have this box of Lego parts and I wondered if paint would adhere to them and it seems that it does! I'll try to do more elaborate stuff here soon, but this was my first attempt to make a "metal" lego bionical, hehe. You guys know I get bored easily...
I did pretty much the same thing (although sloppier) with a Maxilos figure. It really brings out how the bionicle parts were always meant to look doesn't it?
