This is particularly awesome if you’re familiar with chiptunes or just generally appreciate video game music. It’s actually not related to video games at all, but this guy Norman McLaren basically pioneered a very chiptunes sound in the 1950s by painting on analog film. As a side effect, it also allowed him to visualize the sounds he made.
This a series of 3 videos showing his amazing work. The first introduces his process. The second is an early example of his work. The third is a longer, more advanced piece he made in 1971. It has a sound very similar to early video game music that modern chiptunes artists try to recreate… only it was about 10 year before video games had any real music.
