I kept waiting for some optical illusion trick or something

Big fan of Blue Man Group.

In the vid above they just talked about the anatomy of the retina.

... and they kind of get it wrong, specifically because they refer to 'afterimages' when talking about persistence of vision theory, and then act as if the 'reseting period of the eye' is all rod and cone cells firing in unison at a framerate or something, and our brain is filling in the gaps of this constant full retinal reset (nothing like this happens).

'Afterimage' is caused by fatigued cells that have been overstimulated, made to release more neurotransmiter than they can replace. You stare at something red, then look at a white piece of paper (which stimulates all 3 cone cell varieties), and the red object from before appears as a green afterimage on the paper because the cones in the red wavelength are tired. This castle post was an 'afterimage' demo - http://www.videosift.com/story.php?id=3783

Persistence of vision is very complicated; depends on amounts of spatial displacement between frames, amount of time between frames, amount of stuff in the frame,... its weird. The brain sees this and decides whether it sees motion or whether it sees jerkiness. Talking about the brain skipping over black spaces when watching a movie projection is strange; its not like we have photoreceptors for black, so theres just nothing to see...

I'm glad this group employs some talented drumline guys. It sucks they don't employ any neuroscientists, though ; )

They're performance artists: they don't HAVE to get it right. Red, Green, and(nakedpeople) Blue.

Just goes to show... You can't trust anything you read or see on the internet :-P ~

You're complaining that they don't do a thorough lecture on optic neuroanatomy in the span of a five minute song?

Talk about high standards... ;-)

swampgirl, if you have seen that live show, on teh side of the stage there are two tall tubes of water, and there are statue looking things surrounding them, in the show they start spinning and it looks animated. they barely show it in this video. you probably won't read this as you posted almost an entire year ago
