There's a (not so visible) info button top right. It says:

    cachemonet is an exploration into the serendipitous collisions that
    occur between two randomly generated arrays. the arrays contain a mix
    of custom and found .gifs sourced from tumblr and are set to
    music. the output is autonomous, generative, art made possible through
    curation & code.

You can even turn on sound...

and it sounds like "cash money"

That probably depends on what is being displayed... at some point I had sounds of USB connect/disconnect (possibly from the Windows 7 era).
