Rapid Mockup Tools
I’ve used Balsamiq Mockups (thanks Dave) to mockup an image cataloging interface (for a grand total of one end-user, who still hasn’t used the application, but don’t get me started).
In a recent post on WebWorkerDaily, I read about another Adobe Air-based rapid mockup tool: MockFlow. One of the interesting things about MockFlow is its multi-user capabilities. And one of the ways it differs from Mockups is that it assumes multiple pages from the start and has a method of linking them together. With Mockups, it’s mostly just one screen/page at a time. Certainly worth looking into.
(And just because it’s an interesting idea, you may want to check out Mockup Magnets, for doing the same thing on a whiteboard.)
