Fun fact: the background image is the "BallsMany" pattern included with MagicWB for the Amiga

(To confirm: download the LhA archive from https://aminet.net/package/util/wb/MagicWB21p then open the archive in 7-zip, extract Patterns/BallsMany then load into an ILBM viewer, e.g. https://www.retroreversing.com/ilbm )
