Today I messed around with some simple spectral displays and trying other parts of the Processing API. I have added curveVertex to my bag of tricks. This patch has two curvy lissajous spectral displays rotating in contrary motion and a set of bars representing linear spectral averages.
This was the first time I put some more interaction into a sketch. I have a key that changes the mode of the layering. I have been working on things and discovering stuff that I like about a sketch but often it goes away when I make the final thing that I like most. So, I made a little mistake in the process and kept it as an option by pressing the d key.
I still have to look into waterfall plots and buffering. Maybe tomorrow.
