Adding other techniques

[DonaldTsang]

Here are three techniques that I think can make origamicons more unique.

• Ink Blots https://github.com/stuartpb/hashblot
• Bubbles https://github.com/dakridge/identicon
• Circular https://github.com/ea7ababe/identicon

Thanks for your input! I am currently busy with other projects, but might have a look at those techniques some time later. Especially the first one (Ink Blots) seems very interesting.
In the meantime, feel free to fork the project and experiment yourself ;-)
