You've probably heard the story about the artist who wore mirrored goggles flipping his vision upside down for a few days. After a while his brain also flipped correcting his perspective. When he finally took off the glasses at the end of the experiment he found that his own native vision was upside down. Cool eh?

Here's a chance to try. The mechanism of these is articulated by looking down into the mirrored panel. You see there a flipped version of the world. Unfortunately your cone of vision is pretty limited. It's intended to be laser cut on .11 mirrored acrylic (mirrored side down, please)which is often labeled as 1/8". You'll also need 4-40 shcs and nuts. Washers completely optional... I can't remember why I included them in the design.
