I think the weirdest and dizzy making things I've seen recently are on some of the sportsground advertisemnts that they paint on the grounds themselves. Not sure if they do this in the US yet, but over here in Australia they've started painting the signs on the grass field but instead of painting a rectangular sign on the field, they sort of skew the shape of the sign so as to remove the effect of perspective that you would see from the television camera position. When viewed on TV, the sign painted on the grass looks perfectly rectangular and appears to be standing up from the ground so all the advertisers writing and logo are really easy to read, as though you are looking at an erect billboard, rather than a billboard lying on the ground.... a bit like what that sidewalk chalk 3d artist was doing. This all works fine until someone walks over the sign and things then take on a surreal look.
