Here are the first two variations I've come up with:

The first is a rubiks cube-esque design that, instead of relying on color, relies on the size of the pieces. The second is similar to the Mass Effect 2 symbol matching minigame for cracking safes. The multiple 'P' looking symbols would be different, I just couldn't be bothered adding separate symbols.
If you have ideas for puzzles, please post them below, I would love to add them into the mod!
