Ruby: The Adventures of a Galactic Gumshoe is a full-cast radio play produced by ZBS Productions.
My sister and I were first introduced to the series through public radio. They're great fun (with great puns).

Do Androids Dream of Electronic Sheep?
This is a flash animation of one of the Andriod Sister's 'speak/songs.' I love the colors and the designs. This person did a great job.

For my family and friends' reference, I currently have:
Ruby 5: The Land of Zoots
Ol' Cactus Kapoor
Ruby 1: The Adventures of a Galactic Gumshoe (on tape, I'd like to have the CDs)
