CARO began life named Houdini. I always name my characters and cartoon figures. They develop personalities and they assume a real identity to me. When Donald Cox at FailSafe Computers asked if he could use my mouse, I agreed. He felt that Houdini might create copyright problems.
I have searched for names, and I've settled on Caro, a Slovak word for Magic. The name suits both my magical mouse and the magic that FailSafe Computer (http://www.failsafe-computer.com) does to solve my computer problems.
