If you look closely at the calm boat dock scene above, the docks are being splattered by rain. The wood is literally degrading with every drop that hits it. The light poles are rusting with every second. The light bulbs are degrading with every photon of light they are emitting. The wooden cabin is degrading, while the grassland outside is rotting slowly. These all fit into the core realization of 4D graphics.
This one is obvious since 4D is time. The different enviroments in the video change over time.
This one tells about the wonders of 4D that the ps3 has!
