This animation shows how the Kameleon Quilt no 1 works.

Please allow some time for loading.

To keep the size and loading-time down, I have drawn the quilt with only 3x3 blocks instead of 5x5 blocks.
The number of possible variations is of course smaller with fewer blocks, but this is just to show how the thing works.

The animation will run three repetitions before it stops. Click the "refresh" button in your browser if you want to start again.
