Here I present pages that demonstrate various symmetries and symmetry groups.

The demos depend on various features that only some browsers may have.

If you can see "Inline SVG" in a box below, then your browser supports inlined Scalable Vector Graphics code.

Inline SVG

If you can see "HTML Canvas" in a box below, then your browser supports the HTML <canvas> element.

This browser does not support the HTML <canvas> element.

Accessing an image's pixel values is something that different browsers respond differently to. When run off of another server, no browser that I've tried will give access to an image's pixels. So one must save the page and run it off one's local storage. That should not be difficult for my Symmetry Explorer page, since it depends on no other files. Even then, browsers' behavior will vary:

Here is a table of what I have discovered for my Symmetry Explorer:
