Today’s illusion is a variation of the Ouchi Illusion where the center circle appears to be unstable and float above the checkered background image.  This was created by French artist Daniel Picon.

The round inset in the middle appears to move.  This illusion, created by Professor Akiyoshi Kitaoka, is a variation of the Ouchi Illusion and yields a really interesting effect. More motion illusions can be found on Akiyoshi Kitaoka’s site.

The Ouchi illusion is named after Japanese artist Hajime Ouchi.  The central disk with vertical black and white bars appears to float above the background with the horizontal black and white bars. This version of the Ouchi illusion was drawn by Japanese profressor Akiyoshi Kitaoka for Visiome in 2005.
