Uhm … this won't fool anybody with more than one eye. It might look convincing in a photo but once you look at it on location it is gonna be instantly obvious that this is flat paint on the ground.
I don't think it needs to "fool" them, just confuse them enough to want to slow down and have a second look..
In my hometown (Portland, OR), there have been several projects that increase the perceived danger of an area in an attempt to slow people down and increase their awareness. I don't know how effective they are, they sure are annoying :)
