Hot Tipper Rob (after one year, our number 1 supporter!) sent us this amazing little piece about strange multi sensory illusions. There are lots of optical illusions – certain shapes fool our interpretive abilities. What is surprising is that visual stimuli can produce tactile illusions.

So it turns out that if you happen to look at a bunch of horizontal lines moving upward on a screen for a while, then feel a little vibrating line with your fingertip, the line will feel like it’s moving. Evidently, the visual lines predispose our tactile sense to interpret motion.

Here’s another one (via Wired) I found interesting. It’s called the hollow mask illusion and, evidently, it doesn’t work on people with schizophrenia.

I wonder if the Jester would see the mask, or the face?
