Mice Farm is an Instagram account that documents their "non-biological evolution research" of old computer mice. In short, they've got tons of mice...

...and each one gets its own individual post, with tons of photos and a little background info. Here's an example of a weird one from H-P:

"Bluetooth PC Card Mouse, first edition, Hewlett-Packard Development Company, L.P., 2006, USA. A rather weird wireless device that was supposed to be charged and stored in a PCMCIA slot of a notebook. As slim as a regular PCMCIA card. Developed (maybe also manufactured) by Newton Peripherals/MoGo."

I don't want to give away their entire store, so please do click over and see what they've got on show. You're guaranteed to see some weird ones you've definitely never seen before.
