I have been evaluating Balsamiq Mockups this week to see what it is all about and to determine if I want to try to get it at work.
Balsamiq Mockups is a tool (built with Flex and Adobe® AIR) used to mock-up site designs and layouts. It has a really easy-to-use, drag-and-drop interface with a LOT of customization options. It has a huge variety of web site elements for you to drop into your mock-ups. In about 15 minutes I was able to put together this:
And that was with very little practice. As I get better at it, I can see it going much faster. I think it would be a great tool for bringing to meetings where site layout and design decisions need to be made, and then to give to the developers/designers to make happen.
I have to say, I am very impressed with the product, and I look forward to using it some more. I have a fairly large site project coming up, and I am going to use Balsamiq Mock-up to do my layouts.
Here is a link to a boat-load more sample mockups. It really demonstrates the power of the tool to build a wide variety of different layouts.
UPDATE: And here is a YouTube video demonstration of Balsamiq Mockups
