|Just to reiterate.  The video effects generated by the boyz at the showz
|ARE generated by the Commodore AMIGA home computer.  (The software used

|called Klide).

That I can confirm.  Two of my old high-school buddies did the Amiga work for
the shows, doing video feedback stuff.  No videodiscs were used, although
they did pipe stuff in through a genlock device.  I'm not sure of the software
they used, though  -- I'm just a unix hack, and am not familiar with Amiga
software outside of Deluxe Paint and Marble Madness... :-)

Most of it they did in real time.  The did some things for us at a party
recently, all really quite nice.  It surprised me that such new, modern
technology could come up with things so reminiscent of 60's and 70's
psychedelia.  In some ways, the feedback started reminding me of fractal
shapes with all the self-similartiy, and then to have it animated in real-time!

They also did the house of cards for the cover of Built to Last.  Check the
liner notes...
