Hi all. If it interests anyone, a 6 minute succession of red, green, blue and grey images, in 16:9 DVD-Video format is available here. The NTSC file size is a measly 102kb. The PAL, 129kb. The DVD will loop automatically and could be used to speed up plasma "burn-in" (run-in) (if you let it run overnight). Please let me know if you think it should contain more (shades). Edited: added the terms "run-in" to make it clearer.
