Indigo first release was free forever, although it’s not available for download any longer. I’m one of the few who still have a Lite license and can take advantage of this powerful prototyping tool built in Silverlight.
Indigo has helped me to demonstrate design, simulate behaviour and communicate specifications with the development team and also with end users.
GifCam is just a cool resource that helps me to share microinteractions implemented with a prototyping tool.
And this ‘Hello World’ example is nothing but one of the design interactions in motion I’ve been working this morning 🙂
