A Looty is a device that allows each of your eyes to gaze into the other. They were originally made by Jim Woodring
, who stopped making them because he thought the effect was probably bad
"I made machines and gadgets, devices to explore with. Stupid things. Like the Looty, which enables your eyes to stare directly into each other. It's a bad invention... I made a few to sell and then stopped because the effect is unnatural and probably harmful."
Oho! My sense of danger was piqued. I made quick stop to look at the original advert for it in the back of the <s>The Frank Book</s> (<-- don't know where I saw this ad, but I did. And now it's disappeared...), grabbed some likely materials and began.
