WireframeSketcher

I've spend a lot of time to find appropriate free tool to make a prototypes for web pages and desktop GUI, but without any noticeable success. And most of the odosh.com was prototyped in Inkskape and Gimp. It wasn't easy cause this tools not designed for prototyping - theirs main purpose to create and edit a vector and raster graphics, but not making mockups. I've heard about powerful tools for ms windows, but this os is considered only for hopeless cases, such as using some bank clients.

One of the most interesting free tool I was happen to find was DENIM. It is very funny and rather handy after some time spend to ready it's manual. But it has objective disadvantage - it is look like real handmade sketch.

Just before I've give up the idea to use professional tool to make mockups, Peter Severin point me his wireframesketcher. Today I've tried it and it gives me all that I ever need for prototyping: all UI components, alignment, grouping, exporting, creating reusable widgets and dozen other attractive features.

Here is my first prototype made with wireframesketcher eclipse plugin.

P.S. Special thank to Peter for the license key :)
