Technical notes

Movie playback may suffer if you have a slow internet connection. You may see choppy motion or unexpected pauses. For the best viewing experience, you should save each movie to your hard drive and open it with a standalone video player (right-click and save):

hue .mp4, .webm, .ogv,

luminance .mp4, .webm, .ogv,

size .mp4, .webm, .ogv,

shape .mp4, .webm, .ogv.

Each movie is ≈13 seconds, 5 megabytes (depending on the codec), and 400x400 pixels. The movies were tested using QuickTime Player 10.0 and VLC 1.1.2. The demonstration page is valid HTML5, and was tested in Internet Explorer 8 (Windows XP), Firefox 3.5.1 (Windows XP), Firefox 4.0 Beta 7 (Windows XP), Opera 10.63 (Windows XP), Safari 5.0.3 (Mac OS X), Firefox 3.66 (Mac OS X), Chrome 8.0.552.215 (Mac OS X), and Opera 10.63 (Mac OS X).
