If you look directly at the "spinning" ball in this illusion by Arthur Shapiro, it appears to fall straight down. But if you look to one side, the ball appears to curve to one side. The ball appears to swerve because our peripheral vision system cannot process all of its features independently. Instead, our brains combine the downward motion of the ball and its leftward spin to create the impression of a curve. Line-of-sight (or foveal) vision, on the other hand, can extract all the information.

Artists do something zealots can't stand: They break down divisions between people.

A few minutes before 8 o’clock one Sunday evening last July, around 600 people crowded into the main conference hall of the South Point casino in Las Vegas. After taking their seats on red-velvet upholstered chairs, they chattered noisily as they awaited the start of the Million Dollar Challenge.

Magic Carpets se déploient sur le sol de la cour intérieure octogonale de Castel del Monte, datant du XIIIe siècle. Magic Carpets revisite par le biais de l'art numérique, la tradition de la mosaïque très présente en Italie, qui préfigure le pixel.

Finding influence from Land Art as well as specific works like Suprametist painter Kazimir Malevich’s Black Square, Rousse pre-dates the modern trends of illusionistic installation, having perfected his trademark geometric style and his fondness for desolate locations decades ago. According to his site’s bio, Rousse considers himself a painter, sculptor, architect, and ultimately a photographer, but considers his raw material to be his great inspiration: Space.

This is a simple but a goodie. Watch as the balls rotate in a circle ..but focus on one ball at a time and notice that it follows a straight line. Also, watch at the moment when there are only four balls moving, it forms a rotating square between the four balls. This is just another example of looking deeper into something so simple and discovering a hidden pattern.
