Yesterday, while I was out shopping, I found a necktie that is legitimately disorienting to look at. It's red with black diagonal lines, but the lines get narrower and wider, and closer and farther apart, like the Doppler Effect. Focusing on it actually made me start feeling ill a little. Looked up the manufacturer, and it's Australian, because of course it is. Everything else down there wants to kill you, why not a necktie?
So I bought it.
