Although (to my knowledge) the phrase Silicon Heaven was first used in a magnificent Grant & Naylor show Red Dwarf, the Internet Archive: CLASP is doing a fine job of trying to make one here on earth.
I have spoken to a number of people in the past on this subject, not least Pete and Andy Hood of AKQA when last in New York, but to be honest, I've never really had a bit of a dig about to see what was out there.
I'm glad I did, because not only does this offer some hope for those mini-masterpieces created by true pioneers, but they are part of Archive.Org, which has groovy features like the WayBackMachine (ever wondered what the Microsoft site looked like back in '96 when the didn't really believe in the Internet?!) and a real mother-lode of music and audio files. I just did a search for 'Hollingsworth' and ended up listening to the excellent Phil Lesh and Friends.
I apologise, I appear to be a little linky tonight!
