Tron: Disney on Ketamine

Drugs experience has been sneaked into films in all manner of subtle and not-so-subtle ways (c.f. the Beatles' Yellow Submarine)... But here, in the 1980s, is Disney's own film about "going into a computer game"... just so happens the games experience as portrayed here has a striking resemblance (right down to the sound and everything) to the "K hole" of the ketamine trip...
