I've just come across ASCIIMathML. It's superb!

e^(ipi)=-1

mu = E(X) = sum_x.x*P(X = x)

sigma^2 = V(X) = sum_x.(x-E(X))^2

Update: there appears to be a bug in Chrome's rendering of these formulae in that the first xs should appear under the sum signs, not after them. I've added some '.'s to make the meaning clearer for Chrome users.
