I saw this on Twitter earlier today. One guy said "RIP Benoit Mandelbrot. Thank God he wasn't murdered. It would have taken the cops forever to draw the chalk outline."
If you search on Mandelbrot fractals under images, you'll see how incredible they are.
I think this is also what they were talking about on a snippet of a news story I heard this afternoon when the reporter on NPR or BBC was talking to a mathematician who is a crochet artist about crocheting examples of this theory. She added stitches to show the space and create the roughness. It helps visualize the forms, I guess. I'm pretty sure this interview was a spinoff of a discussion about Mandelbrot.
