Cryptozoologist 
Cryptozoologist is a fun little gem written as part of the Gem guide project.
Cryptozoologist generates random strings from animal, clothing item, and color pairings. You could get something like "orange-clownfish-turtleneck" or "magenta-three-toed-sloth-shoe-horn". It's fun and silly - it's also very simple, which is why it is used as an example for the Gem guide project.
This gem is still in active devemopment; complete documentation will be added as the gem (and the Gem guide) progress!
(No, really, it will be added: it's part of the guide!)
Installation
Add this line to your application's Gemfile:
gem 'cryptozoologist'
And then execute:
$ bundle
Or install it yourself as:
$ gem install cryptozoologist
Usage
Right now, this gem doesn't do much of anything except over architect a series of word lists.
Get a random animal:
dictionary = Cryptozoologist::Dictionary.new
animals = dictionary.animals
animals.sample
