Funnest print to watch!

I was digging through my grandfather's attic and found a strange cube with numbers all over it. I decided to copy all the numbers and input them as G-code into my machine. This was the result. I am not sure what it is or where it comes from but sometimes late at night when everything is quiet I can hear it buzz. Patterns are inside and out. Print with no infill no support and with a brim.
