Morning, I created this as an extended-weekend project, after realizing that I'd need these hashes as a part of larger project I'm working on.

Basically, Text goes in, Picture of a Robot comes out.

Where I'm using this is sort of like an identicon, to help quickly identify a poster's 4096-bit public keys, and see if you're talking to the same man.

Is it perfect? No, but it's a quick visual guide to any text, in the form of faces, which are easy for people to remember.

What are the odds of a collision? How many unique elements are there that can make up a robot?

this is cute. if anyone is looking for a more abstract approach i threw some code together a year ago that generates colourful "mosaics" - http://www.acooke.org/hash-icons.html (i really need to improve the page and release the code...)

Any chance of open-sourcing this? :)

If you use all three sets, and enable backgrounds, the collision chance is much lower.

Each Robot is made up of 6 sets of 10 choices each, plus backgrounds.

It's not perfect, but it's enough to give you a basic view into "Is this the same guy or not"

vladev- Sure. It's on Github; Written in Python + Tornado. If you're interested, email me.

I'd rather clean it up, but if you're a Python guy, you could help ;)

I love this, simply because http://robohash.org/mattbearman kinda looks like me :D

My one criticism is that it took me while to figure out (and I'm web dev) It wasn't clear until quite far down the page that you need to just put the text string after the URL.

I'd recommend having a text box into which pasted text can be robohashed prominent on the homepage, as well as clearer instructions.

Edit: just noticed there is a text box, was that there before? It could definitely be more noticeable :)

I love the mosiacs; They remind me of a prettier version of identicons.

My concern was just that people won't remember a random pattern of dots very well.
