We’ve covered a variety of mockup applications through out our properties. Having a variety from which to choose is always better than not especially when so many tools provide their own unique set of features.

Pencil Project is another mockup and prototyping tool that looks to prove to be a solid, viable options.

The nice thing about Pencil Project is that it doesn’t specifically target the web or application interfaces – it provides the ability to work with documents, presentations, pages, GUI’s, and so on.

Definitely worth a look!
