I am not normally a big fan of quick and dirty mockups – I prefer to create hi-fidelity screenshots because I am impatient to see ‘how it will look’ . However, for one of the ideas that I am tooling around with, I decided to create some mockups to begin with… I stumbled across balsamiq and have been using it through the day today.
I am very impressed at how quickly I am able to produce stuff by using it, especially since I have been using their free version.. Need to check out the paid version and see how it is better. BTW, I have no relationship with balsamiq
