On the Shift8 blog there's a recent post talking about moving your site away from a CakePHP implementation and towards Lithium with some help from some helpers.

I love CakePHP and I love Lithium. I imagine many other people will also love both or one or the other or parts from one or the other or neither or enough already. I also suspect that many people will find themselves moving from CakePHP to Lithium. I believe it will be a somewhat common and natural transition. However, we're missing something. Oh right, tons of helpers and other classes!

To help bridge the gap, he points out a set of helpers from Alexander Morland that can aid in the cause. He's rewritten some of the basics - the time, lists, number and form helpers.
