I'm just coming back to processing from a few years ago, when I used play with it in Art School. It's developing so well, and great to see the quality of projects, it's very exciting. 

However, now days im looking at it for with a few different interests. I'm a usability designer, and have a few question / ideas, I would appreciate some feedback on. 

When looking at the Cascade project from the nytlab, the first thing that jumps into my mind, is how much UI designers need to visualise (make meaningful) user interaction data from early stage prototypes. 

If you could have a live realtime data visualisation such as demonstrated in nytlab, to show custom data gathered from a prototype ( drop out points, form input, mouse activity, clicks etc) layered over a hierarchal tree structure of a website (or interaction targets), you would have a very interesting tool when running usability test, beta site launch etc. (Bring on Minority Report)

I guess my questions are;

1. Have anyone start or developed a open project like this? 

2. Are there any tutorials, which I could look at around this space. 

3. Does anyone know how long (really roughly) it would take to develop something like this in processing? 

I may be able to get some funding to develop such a tool from my clients. Were developing an online sports game in MongoDB (socket.io) at the moment and just about to go to usability lab testing phase. This tool would be awesomely useful to someone like me. Gathering data, and even cognitively processing the data is a total pain and make iterations based on the data really slow, if we had a dynamic solution it could really help. Open source project of course.

Anyone interested?
