Bravo! It's so fun and... whatever that word is that is a mix between inspiring and intimidating... to see journals of projects like these where so many different interests and passions come together. I loved the visualization exploration, too - aside from the lines, most of them didn't really communicate anything to me but I was surprised at how well the circles one worked.
The small clips I recorded don't really convey the connection as well as when you're standing right in front of it. You see the connection between the keypress and the visualizer much better when it all works as one.
