Hi Feng, Anytime the word 'prototype' is involved, it lights up the eyes of an ux/interaction designer. :) We love prototyping. We love creating rapid prototype even more - it saves time and can give others (clients, stakeholders, etc) a rough idea of what we are trying to describe quickly. I've given it a quick run through and it seems like a fairly easy to use program that works with very low load time. It also just work (at least of the times I have tried to run it). Kudos for putting this together. The somewhat low learning curve should encourage usage from different users. I know I would. Thanks for sharing.
