Clickable Prototypes
larrywright: I've been doing just standard HTML mockups, often with some sort of generic stylesheet, so that I don't have to spend much time fiddling with CSS. The things I mock up are typically applications for internal use, this wouldn't work well for client work I would guess.This works well for a generic stylesheet: http://www.mostinspired.com/blog/2009/01/28/rapid-interactiv...On the most recent application that I did mockups for, I ended up taking it a step further and building a quick prototype in Rails that I populated with dummy data.  Our final development will be in Java, so this is throwaway code, but it was useful for working out how some problems would be solved. I doubt that I would do this for most things, but in this situation it was beneficial.
