After I wondered whether 3D might not still be cool, I have a definitive answer: it's hot, hot hot! Not only are the hottest movies coming in 3D, but now it seems like the new thing is to make your own 3D images.You can use this iPhone app to do so, or you can spring for the
Holga 120-3D Stereo Camera ($120).
Besides looking like a bizarre double-lensed camera for a two-headed alien, it lets you produce your own 3D pics.
Bust out your chicest red and blue glasses and go to town.
