This is a simple Occam's Quilt puzzle (size 4x4). To return to the Occam's Quilt page, click on the "End Animation" button. The animation will loop repeatedly, so don't worry if you miss something the first time through (or the 6th time...)

This animation will use yellow boxes to highlight the squares in the puzzle that it is swapping. Notice that the puzzle starts out with black outlines around most of the squares, and as the puzzle becomes closer to being solved, the black outlines disappear (this is using the QUILT2 image set... they would be red outlines when using the QUILT image set).
