See http://www.infoverse.org/l2dsspace/ and watch the quicktime demo.
From their site:
[Liquit browsing] has it's greatest strength in comparing a lot of information
objects at the same time by making it possible to perceive
very high information densities with up to 7 quality dimensions
simultaneously.
This is achieved mainly by optimizing visual interactive details
and introducing liquid browsing as an interaction method
to solve the overlapping problem of interactive 2D scatter graphs.
This is a kind of TagCloud on steroids.
Wanna have.
