I used 'floor' in my prior tests, but changed it to 'round' because of
the very small chance of getting the highest number (at least with my
formula).
Let's hope, nobody has wikified my bad maths;-)

Hmm, I absolutely stink at math, but after a few days of testing: the
"randomness" is a bit disappointing. All my presentations start more or
less with the same set of background pictures, and since most have < 22
slides, some slides never come up in the rotation. Is there a way to
provide metafun with a random seed, say the decimal digit of pi
corresponding to the rounded number of my cpu's temperature (just
kidding)? Or maybe a lua solution would be nice, metafun seems to be a
bit to conservative in its choice of random numbers...
