What is Balsamiq?
Balsamiq is a really nice tool which can be used to create screen mockups. Its cheap to buy, fast to use, has a simple interface and there are lots of downloadable stencils that allow you to get a pencil drawn look for most devices on the market.
How do i user the tool?
Using Balsamiq is via a simple toolbar, which forms a pallet from which you can drag and drop components onto your main canvas. You can then choose to save as an image or even a presentation.
