My sincerest apologies, all! I have been very busy with schoolwork, and finally have a chance to work a little bit on this during spring break. This group of illusions, in conjunction with other flaws of our mind (and the entire lack of evidence for the claims), is what leads me to not believe in the existence of ghosts.
Beau Lotto: Optical Illusions Show How We See
(Wait, isn't this a painting by one of the artists you featured previously?) Why yes, yes it is.
One would think that a 3-D version of this illusion would be unlikely, if not impossible. But to the contrary, it has been done. The creator has yet to reveal how the illusion works.
Color Changing Ring of Dots Illusion
It appears that the dots quit changing shape/color/size when the ring rotates. This is (for those of you who have yet to understand the point of this post) not the case. It is known as change blindness.
"The pair believe the illusion occurs because the areas of the brain responsible for detecting these changes are organised locally - each part of the visual field is monitored by a specific part of the brain. Because a fast moving object spends little time at any one location, a local detector only has a small window of time in which to assess the changing object - and therefore fails to detect the change."
It is the illusion of size rather than the size itself which matters. The explanation for this has yet to be agreed upon by psychologists and neurologists.
The Phantom Spin Illusion
Part 1 Illusion: Top and bottom halves of 'wheel' should appear to move in opposite directions. They also switch directions when the 'wheel' moves in opposite directions.
Part 2 Illusion: The 'wheel' appears to be rotating as 'wheel'-block combination moves.
Part 3 Illusion: Both wheels connected to chain appear to rotate.
Impossible Motion Trick
The slopes appear to move down from the center. A different perspective reveals that the slopes actually move down towards the center.
Odd 3-D Illusions
Floating Cube Illusion
Ames Window Illusion
It's really a trapezoidal window. It appears to reverse direction every 180 degrees, but is really rotating in the same direction continuously.
Well how could this be used to manipulate people?
Gears supposedly spin at a rate proportional to how stressed one is.
