All I can remember is that the pin had a mad scientist and/or electricity theme to it and was visually very dark. I could have sworn it was called "Tesla" after the scientist, but when I search around all I can find is a virtual pin with that name.
This was 10+ years ago so my memory is limited, but I do remember it had magnets underneath the gamefield that would turn on and make the ball go wonky.
Anyways, I know it's a vague description, but anyone got any ideas?
