Threenodes.js is an attempt to create a dataflow environment in javascript and html5. It's a way to see what is possible to do in the browser. I had a little list of interesting javascript libraries to try but never had the chance to play with them.
This started when yahoo announced that they wanted to sell delicious. I quickly started to play with drupal to have an alternative in case the website would have closed. In fact it was just putting the right ingredients together: prepopulate, views, taxonomy and some little javascript. Nothing fancy.
There are some additions to my previous sketch. Some more post-processing effects (mainly noise and displacement), two new elements, a new beat detection method, ... But the big change is that I've added some keyboard shortcuts to change "big" variables (frame duration, effects, camera, ...)
I really like soundcloud, there are great tracks and mix over there. But when I just want to listen to music I find the interface too "heavy". So it was the occasion to play with Jquery and the soundcloud API.
