5 kilometers down. A 2 mile wide dome is located. The artificial sun rises over the horizon. Peeking over The Dark Forest, and eventually over the grass fields of small town Smileville, population: Only 8. The artificial sky changes colors realistically, to a sunset purple, to a natural blue. Looks like it's another day of play for The Smiling Critters. All the while secret hidden cameras turn on, recording from afar, or up close. Waiting for anything interesting to happen.
