ruby_identicon 0.0.4

A Ruby implementation of go-identicon by Damian Gryski RubyIdenticon creates an identicon, similar to those created by Github. A title and key are used by siphash to calculate a hash value that is then used to create a visual identicon representation. The identicon is made by creating a left hand side pixel representation of each bit in the hash value, this is then mirrored onto the right hand side to create an image that we see as a shape. The grid and square sizes can be varied to create identicons of differing size.
