Hey /toy/ how about this:
Recreate an iconic scene using action figures. It could be a movie/TV scene, album cover, news photo, work of art*, internet meme, whatever, as long as it's something that is ingrained in people's minds. Something, as I said, iconic.
No heavy rules, except just really, honestly do your best. Don't apologize for the type of setup/lighting/camera/whatever, just do your absolute best and let the work stand as it is.
You can use Photoshop, or any photo editing software you like, you aren't bound by making it all "real". You don't have to use wires, or cutouts or alleyway backdrops.

Recreate the scene using something oddball if you like. Kaiju reenacting the Last Supper, Transformers reenacting the VJ day Times Square kiss. Have fun with it. Just do your best.

Here's a couple to get the ball rolling.
*INB4 somebody just takes a pic of one of the Table Museum Figmas. Come on man, that's too easy.
