Apotomo - a Widget library for Rails

Nick S. is one of the students working on the Google Summer of
Code. His project is Apotomo - which aims to move to even fatter
models, allowing you to model widgets, state and all sorts of other
interesting ways to structure Rails code.

So if that sounds even a little interesting to you, check out his blog
