You can choose <strong>color symmetries</strong>. Single color symmetry does not change the colors of the image upon an elementary rotation. For two color symmetry the colors invert. For 5-fold rotational symmetry you get only single color symmetry.

<p>
You can display a local <strong>grid</strong> fitted to the image. You may thus better see the structure of quasiperiodic images. Choose a colour that makes it visible.
You can display a <strong>reference tiling</strong> fitted to the image. You may thus better see the structure of quasiperiodic images. Choose a colour that makes it visible.
For 5, 8 and 12-fold rotational symmetry you get a patch of a <strong>quasiperiodic tiling</strong>. Examine how tiles of the same shape have similar decorations. For other 10-fold symmetry you only see a rosette.<br>
<strong> Note that drawing a large tiling patch slows down everything !</strong>
