Last night, I had to be at work for a public meeting, at which I had do yet another dread powerpoint presentation. (They're overrated, but otoh they do serve the purpose of giving people something else to look at while you're talking.)
As I was finishing up, I remembered that it was 4/1, and thought I should drop something into one of the images. For some reason, it occurred to me that a blimp would be a funny thing to use, and clearly not real or part of the meat of the presentation.
So I dropped a tiny version of Mrs Coulter's airship from The Golden Compass into one of the pictures. But I think I made it too small, since nobody even noticed. Ah, well. But it's very tempting to try again, at least in cases where there's nobody who can be hurt or angered by it.
