I will talk about the geometric features ("curlicues") of quadratic trigonometric sums and discuss how the renormalization of such sums is connected with continued fraction expansions with even partial quotients. I will also explain a recent renewal-time limit theorem for the sequence of denominators generated by such expansions.
