UPDATE: Here's the latest on the optical illusion disaster waiting to happen: the "warning illusion" has been installed, and now you can now see it in action below.
No car accidents have been reported yet, but it's only a matter of time...
Unexpectedly, the illusion appears to work just like those 3D sidewalk chalk art illusions that have deeply permeated the blogosphere these days.
"The optical illusion of an illustrated girl chasing a ball has been placed on the road northbound at 22nd street in West Vancouver. There are signs leading up to it saying 'you're probably not expecting kids to run out on the road' to prepare drivers. The installation is meant to draw attention to the risk of children running into the street and was carefully tested before being put in place. It is in place for a few days only and is being monitored as a pilot to ensure pedestrian and driver safety are not risked. The illusion rises up gradually from about 100 feet away as not to surprise drivers, and it fades away by the time a driver approaches."
