This is not meant to be snarky, but what's the point of this? What use does the pattern being uniquely generated from a SHA of a distinct string have over a random pattern being generated from a SHA of some random string?

Say I'm using this to generate a background image for each post on HN. Also, I want them to be consistent, so everywhere you see a mVChr post it's got a green ringed background.

I could generate a random string for each user, but then I'd have to store it somewhere. It's better to just use the username as the seed.

It's the same fundamental principle behind identicons.

Got it. I can envision the uses for it now. Thanks for the explanation.
