Normal Mapping Without Precomputed Tangents

I came across a very interesting post on performing normal mapping without a precalculated tangent frame. The technique is an extension/optimisation to the one presented by the same author in ShaderX5, and it elegantly and efficiently calculates the tangent frame in the pixel shader removing the need for storing tangent and bitangent vectors in each vertex.
