The TimeGate, used offstage (wasn't built) last year (20 years ago) by the usurper, Nabalac, who tried to convince the castaway islanders to help him overthrow the rightful ruler of Treasure Island thousands of years ago. They were sharp enough to figure him out. Doctor Dexter Daniels (Doc) and Professor Penelope Pinochle (yay aliteration!) figured out how to get the gate to function, so they, along with the other islanders Quantum leaped their way through Treasure Island's history, very nearly eaten by a Tyrannosaurus Rex in the final episode. Penelope busted for stealing historical artifacts and goofing up the timeline, Cabot the Pirate, innocent for once. Original design from sketchbook, photoshopped to death... of a setpiece built as an add-on for the Treasure Island set (built by Peter Wolf) for Kids' Worship Drama at First Baptist Church, Euless. I'll load the photo of the actual Gate that i built soon.
