There is a warning on the front page: "Warning: This page contains some works of 'anomalous motion illusion', which might make sensitive observers dizzy or sick. Should you feel dizzy, you had better leave this page immediately." So be warned. I will not be responsible for your keyboard if you toss your cookies. By way of Rand Simberg.
