The prospect of giant heads with opening mouths reminds me of a stupid little mobile game I made ages ago after waking up in the middle of the night with it in my head, and not being able to go back to sleep until I drew the graphics for it.
In this game, there are a load of heads. Each one is numbered. Their eyes and mouths can open and close independantly of one another. By pressing keys on the keypad, you can make their eyes and mouths open and close. But it’s a bit scrambled up – so when you press to open one head’s mouth, another’s eyes might shut. The idea is to get all of the mouths and eyes closed.
Here’s an animated gif of the graphics.
