I used to have a couple I would attach to coworker's computers randomly to confuse them. Doesn't work anymore because no one uses desktops with PS/2 ports...
Time for an USB-to-PS/2 adapter!
Haha, why would you make it look like a cat :D
Those only work if the PS/2 device can 'switch' to USB mode. I very much doubt the CueCat could ever do this.
