This single still is from the widescreen version of ?The Second Renaissance?, one of the Animatrix animated shorts. It has been considerably scaled back from the original material. It shows more than a passing resemblance to the initial scene from Tron, in which the viewer zooms through a seemingly endless number of slightly different layers at high speed.
Each layer is a conceptual VR, highly stylized and short on detail. It does not matter however, as each passes so fast, they blur together and create psychedelic patterns.
As the destination nears, the layers pass more slowly, and each can be seen to be a repeating landscape like a glowing circuit board, controlling some aspect of the VR. Layers pass like clouds as the destination, a kind of interface is reached. This metaphor, the entire sequence, talks straight ti the id. It presses the subconscious into believing in a beautiful way, that the mind is actually physically entering the VR.
This sequence appears in both episodes of the Second Renaissance, at the beginning of each, as an entrance, then in reverse, as the perfect exit.
