  • [from steve_portigal] Driving a message home with an optical illusion [The Globe and Mail] – [I'm curious how persuasive the illusion is; does it really cause driver alarm, or is it just something different that jars drivers from a state of complacency] Motorists travelling on 22nd Street in West Vancouver will be confronted with a 3D image of a little girl chasing a ball in the street starting next Tuesday…The 3D image will look like an indistinguishable mark from far away, but by the time the driver is within 30 metres, the image of the girl and ball will become clear…“You’ll see this image start to rise off the pavement and it will look like a little child is crossing the street. As you get closer to the image, the image recedes into the pavement,” Mr. Dunne said….Mr. Dozzi said the drivers will be able to tell something is on the road at a far distance and will have enough time to stop safely when they realize it is an image of a little girl – if they are travelling at the posted speed limit of 30 km/h.
