i once did some research into time capsules, and one consistent piece of advice is to make the container as beautiful as possible. things that are pleasing to the eye are treasured even if they have no practical use.

on that note, i get occasional email from a fellow who bought my old 20th anniversary Macintosh (circa 1997) from me when I left New York City. he displays it as a piece of art in his living room, though it still works great and is built powerful enough to boot OSX years later.  look for it on the wall shelf in these photos.
