The covex appearance is accidentally produced by luminance gradient made by a light bulb.

For the retinal image, the right convex-toward-us corner appears to be about twice larger than the left concave corner, but the former is physically 2.67 times larger than the latter.

Takamatsu City Museum of Art
Mr. Hirotoshi Baba, Akashi, Japan, emailed me of a new method to see an image stereoscopically using a pair of glasses. <August 29, 2010>
Any scene appears to be stereoscopic when seen through the pair of glasses off to some extent. Monocular viewing works, though binocular viewing is more effective.

There is a commercial product which uses this effect in Japan, but I have no idea who first discovered it. <March 19, 2011>
