Playstation Japan published a trailer for the game Gravity Cat in January that is just awesome because of a rotating flat that changes how gravity and in which direction works. But take a look at it on your own.
Now, you may assume that everything is animated with CGI and only the actors are “real”. Nope. Almost everything in the room is real actually. Why would someone animate several hundred of things inside a room when you can just flip the room while filming? This is exactly what the producers of the trailer did. The whole making of for the trailer, presented by Playstation Japan.
