Skin Concept:Junkyard Heimerdinger
I feel like this would be a cool skin for heimer because he can have crazy dirty hair with zig-zag shaped wrenches, also has broken goggles. His Q's cannon barrel will be a bent metal barrel in a zig-zag shape with a make-shift body made of junk and shoots out screws. His W can be glass bottle rockets with both a glass and bomb explosion sound effect. His E can be a plastic bottle with nasty green lighting surging within it. Then his R is just a bigger version of all the abilities.
