I had chance to visit CERN few years ago and they still have the cube on display! :)
Back in the Stone Age, before ISPs/PPP/NCSA Mosaic, I remember telnet'ing into CERN (after dialing in and running a terminal emulator to connect to a Sun Microsystems server at work) to run the line-oriented web browser on their system. Only HEP (High-Energy Physics) news/information available back then! USENET and Gopher ruled the roost as information systems at the time...
