Why is this appealing? Is it because it brings back memories of waking up after falling asleep on the couch watching television? Or is it because the pattern and colors can actually be a reasonable accent in a modern living room or decked out home theater? I know, it's because it makes for a perfect companion to the OSX pillow dock and Roland TR-808 pillow.
If that's not good enough, and you really are missing seeing that test pattern on your TV, download it here and see it every day on your computer monitor as a screen saver.
