Classic geometrical illusion 7

since July 15, 2007


"Kyokusei (= polarity) letter-row tilt illusion"

The uppermost two rows appear to tilt clockwise, the next two counterclockwise, and so on. In addition, letter rows appear to move laterally.

This illusion may depend on the Zöllner illusion.

"Buildings along a slope"

In each side, three 'buildings' subtend the same visual angle but the farthest one appears to be the largest.
