DragonFaX's diary entry for today was interesting because it is similar to an idea of mine. I once decided that if I ever became fabulously wealthy (cue laughter), I would love to have a room in the house which would simulate being in deep space (except for the cold vacuum and weightlessness). A hyperrealistic planetarium if you will.
The idea went through several permutations. The original idea involved a spherical room with a retractable gangplank and a chair on a platform in the middle. A bit like the planetarium in Myst, but more deluxe. The stars would be created with fiber optics. Then I decided that it would be more interesting if it involved computer controlled displays. Then I realized that it would probably just be cheaper with a good VR setup or such, so the idea languished.
Oh well, I'm rambling...
