comment How can the Wiener process be nowhere differentiable but still continuous?
@Ilya: It is always good to be careful, right ;-) Yet I think you described the trivial case of self-similarity. It is a little bit like which function is its own derivative? Well, the exp-function, right? But there is also a trivial case: f(x)=0... Yet this isn't very helpful when you try to solve a differential equation...
