The Box-Pair Applet


Instructions

  1. This is a 3-D image formed from two slightly different images.
  2. Focus beyond the monitor to align the boxes. Hold an envelope to the screen between the boxes to maximize the 3-D effect.
  3. Use the arrow keys to rotate the boxes (left and right).
  4. This applet is under construction. Future versions will include full cube depictions, perspective corrections and antiflicker algorithms.
