The chiptune is Moist Mechas by Sim Gretina (https://www.youtube.com/watch?v=T4HUqvzqnEQ)
, which is part of his Royalty Free series. On the subject of chiptunes, I'd also like to recommend the bands Anamanaguchi and Slime Girls.
As for the box: It's a bunch of Alps SKCM White / Black, IBM Model F, and Cherry MX Blue keyswitch keychains, made out of the leftovers from various other projects. To the left is the keyboard module from a Silver-Reed electric typewriter from the early 80s, using a curious stacked spring-dome design that's somewhat like Fujitsu Peerless switches, with some Televideo terminal keycaps. It cannot yet communicate with a computer, and it will take a very long time for me to sort that out. Also, the scattered keycaps are from an IBM Selectric that was irreparably broken mechanically. They're compatible with beam springs, though.
