This automata paper craft is a Iris, based on the military science fiction Stargate, the paper model was designed by billybob884. The iris is a metal covering on the Earth Stargate which is used to screen incoming traffic.
It prevents anything larger than an atom from being reconstructed, thereby destroying it. It dilates and contracts to cover or expose the central part of the Stargate where the wormhole connects. Friendly travellers are identified by a G.D.O. code.
