What about changing it every hour? Then you have sufficient randomness over
time, and no flashy buttons.

Rotating them would seem like a more viable
solution than randomised - We
don't want the situation where every new page in WP someone reads there
is a
new/different coloured donation button where last
week there was none at
all
- to go from nothing to that would be almost as
bad as a flashing "donate
here, now!" banner.
Indeed, that's the reasoning behind the proposed approach. We don't
want it to typically be changing constantly for an individual user.
Yes, a sequential run does introduce various problematic biases.
An IP-address based hack could work, but would need to take into
account dynamic IP addresses and such, without introducing strange new
biases of its own. We'll discuss a bit further - good ideas /
algorithms welcome. :-)
