Brainstorm

As a kind of pictorial graffiti I want to find places that are usually off limits, I've started this with the statues and monuments.  The projection should still have a self aware interpretive comedy about it :D 

I like the Gilliam style; absurd combinations, hallucinatory effects etc..

People - I think it'd be important for the subject to be unsuspecting, not neccesarily of the camera but of what I'm projectiong.
I can't think of a way to capture moving people, so would have to be still, either approach people in public (this is me, not going to happen) or a sat portrait.

Face masks - Clown make-up, stiches (like a teddy or horror), zombie, mime

Urban locations -  A bit hard as quite is quite a graffiti's place, would need to find some places that arn't normally graffiti'd.

Already thought of interacting with statues

Car's (a dirty one? maybe be a bit shiny to work well) -

Pavement - trapdoors, or a pun on the 3-drain superstition

Churches - a mocking religious symbol, maybe a devil banging at the door, or climbing from the floor.

Nature - Bit tricky to find a good surface though

Tree - something cartoony, a small door and windows and a little man.  Or spiritual, fairies
