Dreams
I had a dream that I was involved in a huge project to build an Inform model of the South of Market and the Mission, to be used in a very sophisticated adventure game. One thing that made the dream more exciting was that I was inside the model the whole time, although it was clear that what I was seeing was somehow generated by Inform, and I could converse with other people about the progress of the model ("This is so-and-so's apartment -- in the next version we're going to add a door over here and a daemon that shows changes in the apartment over time"), which was actually kind of like David Gelernter's Mirror Worlds, although I didn't think of that at the time.
My virtual South of Market is a very exciting and dramatic place!
