I like it. I'm a coder / designer and I usually do the layout stuff in photoshop and then add animations when I actually build the product (i.e. Core Animation in my case) but that can cost quite a few build / test cycles until it has the right feel (speed, animation, etc) to it. I'm a huge fan of Quartz Composer but to me it just doesn't feel like the right tool for the job, especially since interactivity (i.e. touching, clicking) feels a bit like an afterthought in there. Also, I really don't like Flash; had to do Flash programming years ago, and can't stand the UI anymore. So this tool looks like the solution that perfectly solves the problem I'm having there. Thanks, I'll play around with it tomorrow!
"I'd like to say again though that supporting more browsers is not one of my primary goals."
But I hope understandable for a prototyping tool. I'll take contributions though.
Sofa still rules! And now in open-source.
Cheers, Koen.
What's Sofa?
This looks pretty nice for designers who happen to know a little bit of code. Most designers I know do their mobile mockups in After Effects so they can really demonstrate interactions and animations.
That's exactly what it was made for.
For some reason it doesn't seem to be working with CS5. I run it alongside Photoshop and it just says "syntax error: Expected end of line but found identifier. (-2741)" for a split second.
Argh, sorry for that. I did not have CS5 to test. I'll see if I can at least put in a better error message.
couldn't it be used for real applications -not prototyping- with phonegap?
awesome work good luck
