insane

adj. mentally ill, mad, crazy; senseless, foolish

INSANE is a proprietary INteractive Streaming ANimation Engine developed at LucasArts, primarily by programmer/game designer Vincent Lee. It greatly compresses moving images so that high quality full-screen videos can be displayed even in hi-res graphics modes on the PC.It was first used in Star Wars: Rebel Assault II - The Hidden Empire and then in Full Throttle and The Dig. It was also used in the 1998 games Star Wars: Droid Works and Mysteries of the Sith. The use for Full Throttle caused some problems since INSANE was intended to be photorealistic, contrasting to the general cartoony feeling. The rendered environment had to be scaled down to match to the rest of the game world.

Insanity, or madness, is a general popular and legal term defining behaviour influenced by mental instability. It is defined by the Merriam-Webster dictionary as a deranged state of the mind or lack of understanding. Today it is most commonly encountered as an informal term or in the narrow legal context of the insanity defense, and in the medical profession, the term is now avoided in favour of specific diagnoses of mental illness as schizophrenia and other psychotic disorders.
