From 10-35 to 1027

1. A very nice zoom-in/zoom-out gadget showing, in a nutshell, what's in the universe at all scales, from the size of the universe itself down to Planck's length. Click here and then on "play" (from 10²⁷ to 10^-35).
2. This one is specific for biological objects (from 10^-2 to 10^-12).
3. And here is a zoom-in into Mandelbrot's set 10²¹⁴ times (this is more exponents than in 1. and 2. above).
