An idea I had was a creature collecting game where their "gender" field was filled with random symbols with no explaination to what they mean.
So that's just the part that generate those, without the atteched creature collecting game.
Too lazy to do an actual edit buttons for now so you just have the randomize, you'll have to poke in the js if you want to be precise (edit the prongs array). Fun button to press at least.
There are currently 8 prong positions with 16 shapes each (counting "no prong"), although "no prong" is more likely to be picked.
