Good to know @Marci. I'll give it a try.

I've used it before. It's a nice way to quickly create interactivity from your sketches (rather than taking the time to translate them to a design program). Really good for collaboration with folks who aren't as computer/design savvy.

Looks interesting but wouldn't it be faster to use a computer?

I never used before but it looks interesting.
