A few things to notice:

• very “rails” light… small controller… very literally a controller.. all the action happens in the models,
• all the specs are for model classes, the controller & view do very little.. although the controller could probably do with a few specs, and
• there’s over twice as much code in the specs than in the working classes.

The spec run:

$rake spec

Note that echo was under development and actually didn’t get finished in time. Also we ran out of time before getting to mindbender.
