And now I'm all the way home. Everything still seems to be here, and there are signs of recent rain.

Note to developers

It would be useful if, before panicking about programs that haven't been run/updated for a month, the computer could check whether it's actually been turned on during that month.

As far as I can tell, the grain on consumer-grade 35mm slide film (Agfa and Kodak, 1958-1998 or thereabouts) is roughly equivalent to 300 dpi on a 6x4 print, or a 2Mb digital camera. (I was scanning them at twice that, and you can clearly see the grains.)

The snag is that consumer-grade (or even office-grade) digital projectors can't display that many pixels properly yet; the best I've seen is 1024x768 with (I think) 8-bit color, so for projection on a big screen you still can't beat slides, even though no-one uses them any more.
