Where would I find them?

Pretty straightforward but I can't seem to find more than just a handful on the spriters resource. If anyone could point me in the right direction I'd be very much obliged.

With this you can make your own animated ones that you can take stills from

BEHOLD! http://eblw.galaxyclock.com/

That page is a reference for the screensaver Pigmask linked to and the Android version of it. There's a ton of images, and they will load slowly, but it's got every single combination, even ones that don't actually show up in the game (because the backgrounds are made up of two layers, not all possible combinations were used). Enjoy!

Awesome! Thanks neonix!

Each combination, and even those that do not actual display in the game.
