Today's Bing photo kinda bent my mind a bit...

Bing usually put up an awesome photo on their search page each day.
Generally one can expect to see amazing natural sites, beautiful places, weird and wonderful creatures and other such things.

Today's photo however, is truly something to behold.
I give you, the world's largest cave - Hang Son Doong, in Vietnam:

Just try get your head around these dimensions - the biggest chamber of the cave is 200m high, 150 wide, and more than 5km long!
