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...
