Does anyone know of a good pack of "Wheel" type images for controls like Trackball, Spinner, Rotary, etc? I'm working on my front end layout filters, and I have some genre logos for things like SHMUPs and fighters, pinball, platformers, but striking out when it comes to logos for trackball, spinner, etc. Those are the main two that I'm looking for, but wouldn't hurt to have logos for other types of controls.
