So, what would be a funky looking dessert?

Apologies if I've missed anything momentous here the last few days, trying to keep up with the yard and helping sort out the stuff from my grandma's estate have really snarfed my happy-lurky time of late - but I Need YOU, flist!

Our youth group's annual dessert auction is coming up this next Sunday and we're ready to roll up our sleeves and come up with something that is both edible and interesting to bring a good price.  We haven't topped our cat-litter pan with crumbled edible 'litter' and tootsie-roll turds in it yet, but I'm willing to try. Maybe a Dalek cake? Sadly there are only a couple Whovians who would recognize them.

Ideas? Things you've seen done that don't involve fondant/ many pounds of frosting/ miraculous baking skills? Humor is good.
