i don't know what it is about these television signal things, but i like them. and in some strange way find them to be really aesthetically pleasing. i think it's the nice chunky bars of primary, and like-primary (well, secondary) colors that i find so appealing.
i don't find them on the tube as much as i used to when i was a kid and when the world of channels was a much smaller universe. now when i see them, i have a tendency to look at them for a while, not just flip by.
