Heh - even talking about matrices like they're always 4x3 or 4x4 (as we're
likely all guilty of doing from time to time) is rather a narrow view of
the concept...


I would "like" to see hardware take a blind leap of faith and provide us with a wider than four simd instruction set, but its  not going to happen, so we all end up thinking in 4x4 usually. Its not narrow, just pertinent.

Just because the world is full of people that think just like you, doesn't mean the other ones can't be right.
