The Sky Factory deals in fake skylights and windows. Their SkyCeilings and Luminous Virtual Windows are photos of the outside that fit into standard ceiling or window grid systems. Fluorescent and LED backlighting is also available. It's like having a piece of Vegas in your own home! Seen here is a backlit Luminous SkyCeiling installed in a medical procedure room.
