On New Year's Day last year after quite a wild party a friend found this image left on a car in the neighborhood.
This is different then most optical illusions it is what I call a before-image optical illusion. You have invariably seen many after-image optical illusions, the type where you stare at an image then look away and see an illusion.
This optical illusion is a before-image illusion, you stare at it and while you are staring you start to see what came before that left this image.
What do you see?
If you are partying away from home please designate a driver in advance and have safe, sane and consensual New Year's Eve experience.
Happy New Years All!
Update: Daria pointed out that the origin of this photo and possibly the real story behind it can be found here.
