i was going to go for a Sim costume, wearing mood crystals I made out of clay and styrofoam:
(darq)
but they didn't stay well, so I went with what I know (wore for my 3rd year, the big head skeleton costume):
friends were: a camera, a Rubik's cube, and a pansy flower)
some houses gave me extra candy because they liked my costume, and everywhere we went, kids were pointing, whispering (LOOK at the big head!) and some kids took cell phone pics XD... so much fun
