Saw a Medusa today! Very interesting looking pin - I actually really liked the cabinet art on this one. It guess it was meant to have translucent flippers at the business end of the machine, and where those zipper flippers half-way up? The post between the flippers was able to be operated as a kicker, by the look of it.

The Medusa was a great looking pin. And the Vector backglass I'm still thinking about...
