Like we needed another reason to love our iPhone 4, but this ramps up it's basic use a notch. How about a case the doubles as an LCD projector, turning any wall into a large viewing surface. Great for those of us who travel and get tired of watching the Simpsons in Spanish. But wait...there's more. It also has a battery pack that adds substantial runtime to your phone. Currently only available in Japan so you better get yourself a proxy if you want one. Watch the video after the break if you'd like to see more.
