UNIVERSCALE

UNIVERSCALE by Nikon

Universcale is a cool little flash app that displays the scale of everything in the Universe

(or at least a lot of things in the Universe) and gives you a scale that puts them all in perspective.

You can see how a single proton compares to a rabbit or how a rabbit compares to the Eiffel Tower or how the Eiffel Tower compares to a planet.
