This interesting paper by Betsy Book (June 2003) describes tourism in graphical virtual worlds and reminds me of the fun trips I had in the Hyper Hovercraft(#94256) at LambdaMOO. I just checked and it's no longer there, although it exists in my personal list of rooms (@rooms). It was a very clever piece of programming - you could climb in with a few friends and take off, swooping over the assembled Lambda hordes in the public rooms. Great fun. There were balloon trips there too - I wonder whether they still exist? Have emailed *research to enquire.
