If you were going to create motion in only 3 frames what 3 fames would you choose?

This is a nice illustration using real pieces to recreate a famous 2-dimensional illusion. This is a good site too.

Parviz has been using the prototypes to display biosensor feedback about the wearer's vital signs, but they'll eventually serve as a heads-up display for displaying other data. Read more...

I had to put this one up. This is a great example of how the visual system tries to resolve the retinal image. Is this a lamp or a woman in a bikini? How does the visual system try to resolve this? After giving it a try - check the answer by clicking on the continue reading link below.

British inventor Josh Silver, a former professor of physics at Oxford University, has come up with a game-changer of a product design with his water-lensed glasses.

These are really brilliant and a refresing way to look at things we take for granted.... http://haha.nu/creative/creative-photos-by-chema-madoz/

 

Magic is very much a sensationand perception topic. How does he do this? What do we know about the brain that might explain this?

I am really now sure to to tie this in at the moment. Perhaps it illustrates the resolution we have with the eye...

One way we can learn about how effortlessly the brain seemingly separates objects out from a visual scene is to examine how the brain has difficulty doing so. Can you see the man in the picture below? More.

 

The visual system works on probablilty and has expectations of the world. This is a good example of what happens when the expectations are violated.

Ever wiggle a pencil in front of your eyes and it appears to be bending? This is result of our visual system having a limitation on the sampling rate speed it has. Remember that vision is a neural activity and neurons have to go through a very brief refractory period before they can fire again. If our sampling rate were higher, this is how something as simple as a rain drop would look - this is very cool!

 

And if you want, go this site that has a water drop synthesizer. Notice how you can change the frequency, variability, and number of drops to make it sound like a sink, bath-tub, or rain...
