In the light of extended cubie puzzles I made a quite a simple but fun puzzle called the Evil Domino(Off of Skeneegee's evil twin.)
It's basically is solving a 2x2 but I am having fun with the puzzle.
Note in the comparison the 3x3 is not an evil twin! I just love the logo alot

Interesting. Is there just a single 2x2x2 mechanism in there, or multiple mechs?

I believe it's a single mechanism with glued on extentions.
