I have noticed that when I look at anything with a lot of closely placed parallel lines (window blinds, a striped shirt, etc.), that the object actually "shimmers" or "vibrates" in a way. It is quite disconcerting. I thinks actually this is an optical illusion caused by the static "interfering" with the ability of the brain to "decode" what it is seeing. I can't stand striped clothes anymore! Anyone else experience this?
