These are cropped screencaps of the .wav file from "Triangle Wave Modulation." The patterns are similar to what you see on an oscilloscope but narrower on the horizontal axis. Because this is Cubase on Windows, the bells and whistles factor is pretty low - the idea is to generate these sound files on the fly with just enough resolution to see them but not so they slow down the music processing while rendering. Saved as a bitmaps, the files are converted to GIFs without losing any detail; each is around 20KB - that's efficient. One thinks of Argyle socks, and Vasarely paintings, but it's just a diagram of a warbling bloop.
