There's something to Powers of

There's something to Powers of Ten Thousand ( which presents the idea of "The macroscope: translucent zooming and panning"), but I think they too easily dismiss the visual clutter/confusion problem. My guess is something about halfway between this and standard pan and zoom might work better (oh, and I want the relative translucency of the layers to be controlled by my eye's depth of focus).
One particularly telling quote: "We have not yet performed any formal user testing." (via xblog)
