I’m just loving Balsamiq Mockups. It’s an awesome UI mockup tool that lets you whip up prototypes in a couple of minutes, communicate ideas and iterate rapidly (did I already say I love iterating!).
The full license is $79, and worth every penny. I’ve now done two full featured UI mockups and they’ve proven a great tool to discuss with the team.
If you need to create mockups for a web service or a GUI, your team shouldn’t be without this tool. It’s also available as a plugin for Confluence and JIRA, which makes it even handier for bigger teams. Support is also fantastic at GetSatisfaction.
Okay, now back to getting more mockups done =).
