Which way is it spinning?
Created on: October 17th, 2007
A 3d wireframe of a doorknob flattened to 2d and spun 360 clockwise. It appears to spin both directions and flip-flop depending on the part of the image your concentrate on.

Are ya'll saying the rotation flips directions, or are you saying that the horizontal spin changes directions. For me all I'm seeing with the horizontal spin is a single motion toward the left. But the knob seems to spin either direction if you were 'turning the knob' like trying to open a door.
Not sure what's so special about it either. Any wireframe image will do it if it's on a spin. Hooray basic 3d modeling though I guess.
The correct answer is "it spins either way at any given time, depending on the perspective". If you study the image long enough, you will come to the realization that when the picture stops at each point just like the frame above in the preview, you have no way of telling if the round knob portion or whether the flat disk portion is in front or in back, because it is a wire frame. There is no reference of depth to act as a guide to tell your eyes what is in front. Therefore whatever your brain happens
it's actually pretty crazy when you examine it frame by frame. when you look at it closely, you see that it in fact isn't spinning at all, it's simply moving right to left to right while pivoting. really great effect, the best part about it is that once your mind gets it moving on one track and it all the sudden changes, it's really hard to "blink" out of it. very cool.
The key is perception I found, at first it was spinning and spinning then I fogused on the dot at the head of the bulb part and using that as a keypoint I was able to at will decide the direction that it spins in. It is in reality only bouncing back in forth as its a 2D image, how ever your perception of this event determins if it is spinning and what direction.If anything in your life teaches you this fact it is this,the image you see in your mind is not the image you see with your eyes, the cake is a lie!
