Think Small - The Scale of the Universe

This is not TG specific, and in fact I didn't think of it as a Writer's Resource until I saw the option in the list... but it is incredibly nifty. Let it load, and use the slider... left goes smaller, right goes bigger...

The only error I've found in it is it gives the size of the known universe as 14 Billion Light Years, when it's actually 14 Billion Parsecs.
