Abstract: The attraction systems include underground or underwater tunnels having a visitor transportation system with ride vehicles and multiple audio and video systems for providing an experience of three-dimensional (3D) or four-dimensional (4D) video installations. In addition, the attraction systems may have various special effects devices to enhance visitors' experiences. These underground or underwater tunnels may be built in cities, and especially, in historic city centers.

Abstract: A system for investor-driven creative production, in one example embodiment, comprises a receiving module to receive metadata associated with the creative production. The metadata can be received from a creative content provider via a creative content interface and include a description of the creative production and an investment goal. The system can further include a posting module to post the metadata to the creative content interface and the receiving module to receive an investment in the creative production from an investor via the creative content interface. The system can further include an investment processing module to determine that the investment goal is reached and a production initiation module to selectively commence the creative production based on the determination that the investment goal is reached.
