Anyone have a clever way to retrieve for example, items 0-29 from an
array of size N>29, in random order? The catch is that I dont want to
print any items more than once and I dont want to miss any.

This is for a tag cloud where I have sorted them by popularity but now
I need to display only the top 30. I do this now but they are in
order of popularity and its not really a 'cloud'. If I could retrieve
the top 30 in some random order, it would look better.

Thanks
