This is brilliant because in a limited way it hearkens back to the far more general game of the early Apple IIe era in the early 1980's which Robin Warinett wrote (the writer of the Adventure and BASIC programming cartridge for the Atari 2600), called Rocky's Boots. In that game the logic gates are used to kick a boot at shapes passing through a conveyor belt in different patterns and you had to time the boot to get desired (different per mission parameters) shapes.
Although this is far more specific and only has 2 things (nut, rock) it's still spiritually very much in that vein which is why it struck a chord with me.
Outstanding work, gave you an itch follow, if you like the thing(s) on my page(s), consider doing the same.
Cheers!
