Tags are going n-dimensional…

Ben (the new-look Ben) & Co have implemented a nice 3D tag system using 2 spatial dimensions and the 3rd with colour.

Also have a look at the “schematic”/time-linked cross-tagging presented at the recent “technology 2.0″ event.

This helps pave the way for some nice n-dimensional data visualisation techniques: 3 spatial dimensions, font size, colour allow 5 dimensions out of the box, then add density (spatial clustering) for a sixth, and animate for a seventh (of course you could use orientation to create each word as a vector to take you to ten, but that might be getting a bit silly/incomprehensible).
