WeaveSilk

 One of my favorite websites has always been weavesilk.com. It's another color therapy-esque site that you can make neat and intricate designs with (plus, it comes with nice, ambient music!). Here's a few "silks" I made.

This one, along with the next, took relatively little time.

I didn't name the first and second ones because they were mostly just warm-ups. The next ones will just have their names beneath.

Heat Death

Through

Antigrav

Icarus

Bleeder
