Saw a beautiful rug at [url]http://islamandart.tumblr.com/post/47334157323[/url]. More info and an animated gif at [url]http://mathhombre.tumblr.com/post/47378241170/saw-this-beautiful-rug-at-islam-and-art-and[/url] [br][br]Like the tessellation in it, but I also loved the inferred motion. So I made the tessellation to animate.[br][br]On edit you can change the shapes. Step 1 lets you see how they are put together, and Step 2 shows the full effect.
