Where was it that I went tomorrow? Tomorrow I went where I am., San Francisco, CA, November, 1999
The exterior cabinet is 2 feet wide, 2 feet deep, and 2 feet tall. There are two scale models of it on the inside (the small one is inside the medium one). Each of those cabinets is on runners and can be pulled all the way out of the larger cabinet (though not shown in the picture…I didn’t know much about documentation back then!).
