+Shifty was [Stepladder](https://github.com/joelhelbling/stepladder), which grew out of experimentation with Ruby fibers, after reading
 [Dave Thomas' demo of Ruby fibers](http://pragdave.me/blog/2007/12/30/pipelines-using-fibers-in-ruby-19/),
 wherein he created a pipeline of fiber processes, emulating the style and syntax of the
 \*nix command line.  I noticed that, courtesy of fibers' extremely low surface area,
 fiber-to-fiber collaborators could operate with extremely low coupling.  That was the
 original motivation for creating the framework.
