What would earth look like if the oceans were empty?

Question: We've all spun a globe or looked at a map of the world, but I've never seen one with the oceans empty. What would the world look like if oceans never existed? I think a 3-D image of earth would look crazy without the oceans...you would see the continents like enormous mountains, and everything would basically be connected by vast, empty valleys where the oceans are supposed to be. I'm not looking for any lame, sarcastic global warming answers, but are there any 3-D models (think along the lines of google earth) of the world, without oceans?

Answer: Very Dry. Actually there are such maps available showing the dry land and the ocean floor on the one display. You might try www.natgeo.com and see what they have.
