Through The Viewfinder is a technique using an old TLR Camera such as an old anscoflex with a top viewfinder, building a light blocking contraption around it and shooting the viewfinder with a digital camera. The unusual distortion is due to the viewfinder's bubble glass, the dust and dirt give it a rustic, old feeling... I love the dreamy look.
