Hm, is using tau a standard convention?

I've thought pi is horrible... and adopted using a loopy pi as 2pi. I loop the first vertical line over the horizontal, right, and then make it the horizontal, and so on. If that makes any sense.

I'm thinking of making a LaTeX package containing it... (and also some other personal conventions)

Also, to strengthen your point, 2pi makes the radian system a lot more natural.

I made up the usage of τ myself, partially because of its typographic similarity to π, partially because it leads naturally to the usage "τ = turn". It's too bad that π has two legs while τ has only one; it would be poetic if π were 2τ, but it wasn't to be.

N.B. I have a secret master plan to spread the use of τ, but this comment is too small to contain it. ;-)
