A tag cloud as starmap?

Hey guys. I’m looking for examples of a specific effect…

I would like to create a dynamic starfield based on a tag cloud.Larger tags = larger stars etc…

Before I try to think out how I will do this I was hoping that perhaps someone else out there has done something similar that I can reference.

If anyone can think of anything remotely similar I’d be much obliged. I’ll also post anything cool I come across in here in case you guys are interested.

Thanks all!
