If I remember this now the Burroughs/Gysin Dream Machine had a
frequency between 8-12Hz (intended to correspond to the alpha waves of

I think you can find DIY instructions on the net, but it is *not*
receommended for anyone having epilepsy or similar problems.

As for a suitable computer display - perhaps a LCD-screen with long
decay time?
