I remember an Amiga optical mouse back in 91 that needed a special mouse pad with a grid pattern to work.
There was the Dale Luck "Boing! Mouse" that was a 3 button Sun mouse modified to work on an Amiga, with a plastic and rubber pad set with lines in a grid; and a Golden Image mouse that used a piece of cardboard with dots on it; the Golden Image mouse shows up on eBay, but its pad was usually eaten by the family dog and showed up it the dog's poop.
Boing! Mice are hard to find and can sell for in the $70 USD range; Golden Image mice are best fed to the family dog to help clean them out from too much cardboard ingestion.
