I also made a mouse jiggler because of a former job’s inflexible screen locking policy. I made mine hardware with a small MCU that plugged into USB and looked exactly like my work-issued mouse (vendor id, device id, etc) It was hardware because I didn’t want it to show anywhere (we were technically not allowed to install unapproved software even if it meant we couldn’t do our job and it was a selectively enforceable fireable offense) It worked very well and was shaking 5px left 5px right every minute. It was so little that you wouldn’t notice while actively using the computer.
