Amazing zomby show

Three psychology researchers (including the Queenslander Matthew Thompson) have hit upon one of the most amazing distortion illusions I've ever seen: http://mbthompson.com/research/

While you're gazing at the cross in the middle of the screen, nothing prevents you from taking a brief glimpse at times, to the left or right, just to make sure that the video creators were not cheating.

The viewer's situation reminds me of what a driver might see when he's traveling at night along a narrow mountain road, with his eyes fixed on the road ahead. This was often the case back in 1993, when I resided for three months at St-Pierre-de-Chartreuse, which is separated from the outside world by a treacherous winding trail through dark gorges, between cliffs and ravines.

I can now understand retrospectively why I often imagined, in the darkness, that I was driving along a mountain road inhabited by the medieval ghosts of Saint Bruno and his fellow monks.
