Outstanding photographer and good friend Peter Guttman has a very cool app out on Apple for itouch and phones. It is called Beautiful Planet and will take you to some amazing shots by Peter shot on all seven continents and in 160 countries. Peter is an author, adventurer and above all captures magic with his cameras. I have had the pleasure of his company in Kenya, Latvia, Lithuania and Russia. Seeing the world through his lens $2.99, a bargain!
