Hello, Pittsburgh community. There have been a number of successful threads on the main IxDA discussion forum, debating the merits of different prototyping tools, or at least mentioning the existence of many. What do you find to be the best, or easiest-to-crack-into, tools for designers to create interactive prototypes? For articulating concept; communicating behavior to developers, clients, or other stakeholders; and testing for success?
Here are just a few mentioned in threads on the main forum within the past year.
