Victoria Skye: “Skye Blue Café Wall Illusion ”. USA
Author description: Do the dark blue rows appear to slant? Surprise! They are completely straight and in parallel rows. The rows appear to skew due to the contrasts and variants in light and color as well as the varying angles of the diamond targets at the intersections. Blurring the image dissipates the illusion by dissolving the contrasts and angles. The Skye Blue Café Wall is an adaption of previously discovered versions. Richard Gregory made the original illusion design famous after documenting the illusion seen on a café wall in Bristol England. Professor Akiyoshi Kitaoka has created multiple versions of the illusion that include the contrasting targets.
