Put a scale symmetry exactly on top of a rotational symmetry. Enjoy.

SuperSym: A symmetry-based doodling toy. Draw symmetrical things. Feel soothed by them. [via mefi projects]

I have been playing with this nearly every day since it was posted to projects, and it's still just endlessly entertaining. I mostly don't play with the fancy loadable symmetries -- I just like a scale symmetry on top of a rotational symmetry, which provides a kind of 3D well of scribbling. It is deeply, unendingly satisfying even if you literally just scribble on top of it.

Another fun thing to do is to draw something relatively simple -- even a single straight line -- and then change the symmetries underneath it and see what happens.

It is a totally lovely little thing!

Ohhhh … you have to Edit sym. first. I was pointing, clicking, nothing happening, checking for blocked JavaScript, …

Oh, yes! Sorry! The Projects post included a demo video that I should have put in this post.

Just a simple rotational symmetry is like having a free-form spirograph in your browser. Totally mesmerizing.

Unfortunately, the name SuperSym is a tad misleading because it doesn't seem to let you create a symmetry between fermions and bosons using a Z_2-graded anticommutative extension of the Poincaré group.

I disagree: the Poincaré group was notoriously opposed to doodling toys and that so-called exclusion actually reflects the deeper beliefs of the organization.

I feel like a six year old with a beautiful new spirograph. This is a delight.

I really enjoy this. Thanks for sharing it, jacquilynne!

I have been reading the latest Sanderson, and now I know what Pattern looks like.

Very, very cool.

Glad some folks other than me have enjoyed it!

I wanted easier color-switching when drawing, so I added a "color history" system that stores the last 5 used colors. Click on the color history buttons, or press the 1, 2, 3, 4, or 5 keys to quickly switch between the last 5 colors.

If you've already loaded the page in the past, make sure to hard-reload (something like control-shift-R) to ensure you get the latest source files.

After only four hours, I declare this the most delightful diversion on the Internet. I literally did not worry about a single thing while I was exploring what it could do. The simplicity of the color picker is deceptive; the range is astounding.

I liked it.
