Maybe I'm just imagining this, but I seem to remember seeing an example of the word "Push" that when viewed upside down read as the word "Pull". My fever dream or a reality?
Holding a mug close to my face, there is an interesting effect. It's not like other things and I can't duplicate it with other objects. [more inside]
What's this illusion called? The full moon is rising, but has not yet cleared the horizon. The bottom of the moon, however, appears concave, its outer edges bending up from the horizon. (Image link inside illustrating this concept). [more inside]
People often put on a 'funny voice' or accent for emphasis or just in general conversation. This is possibly a reaction to their company but possibly some kind of psychological obfuscation?
Does askmetafilter know of any any research into the way people put on funny voices for emphasis when they say things? Accents and intonations etc.
Google has not been kind to finding ideas or starting points.
Last night I experienced a strange optical disturbance/illusion/vision problem. What's that all about, and should I be concerned? [more inside]
and this hypnotic diagram
reminded me of a science fiction short story premised around the idea that breakthroughs in psychology and applied mathematics had made it possible to design two-dimensional black and white images that would produce extreme effects in anyone who looked at them. The result was a society in perpetual counter-terrorism lockdown. An image like "The Parrot" could cause immediate seizures and fatal strokes, and one terrorist sneaking a placard of it into the Superbowl could not only kill everyone in his immediate area but also viewers at home. Our main characters in the story are tweens who attend a school with translucent windows. They've gotten their hands on a low-powered nausea-inducing image and they've formed a secret club to take turns looking at it. Where can I find this story? [more inside]
Can you help me find instructions for a magic trick or illusion that involves 2 or more ropes going through a large tube? (I believe the ropes are linked by washers inside, and so by discreet pinching, the user can produce baffling effects when a mark pulls on a rope.) [more inside]

How does this card trick/illusion
When I look at an image (on my LCD computer screen) that is composed of a combination of solid colors separated by black borders, I perceive the colors as appearing on different planes of depth, as if the image were three-dimensional. If I close either eye, the illusion collapses. Am I the only one affected by this, or is it a consequence of the way LCDs display color? [more inside]

My bathroom has mirrored walls instead of tiles. When I look at myself in one wall/mirror, I seem slightly shorter and wider than I seem in the other mirror, creating the illusion of a 5 lb difference in my appearance. Is there a way to figure out which mirror (if either) is accurate?
In around 1986/87 (+/- two years), I saw an edition of The Last Resort with Jonathan Ross (failed UK attempt to copy the Letterman chat show format). One of his guests that night was a freakish guy, possibly French, who swallowed things and then extracted them through his stomach. So, he'd swallow some string, then stick a skewer or something through his stomach wall, and hook out the string. Yes, it was that disgusting.
1. Was this real or an illusion? From what I can remember, there were close-ups and it didn't look like it was being faked.
2. Who was this man?
