Here’s an intriguing device on Instructables- The Looty was created by artist Jim Woodring to allow the users left eye to stare directly at the right and vice-versa.
Jim made and sold these devices for a time, but eventually discontinued the item. In an interview over at Hour.ca he spoke regarding the projects demise –
“It’s a bad invention… I made a few to sell and then stopped because the effect is unnatural and probably harmful.”
All the same, it’s an interesting example of invention for self-exploration. If you do decide to build the Looty, do be mindful of any possible strain on the eyeballs – they’re hard to replace!
