Abstract: An origami is a combinatorial object consisting of squares and gluing rules. It yields a closed surface and, by variation of the translation structure, a 1-parameter family of Riemann surfaces and finally an algebraic curve in the moduli space of curves of a certain genus.

In the talk, I shall concentrate on a particularly nice example in genus 3, which has several spectacular properties: for example, the associated curve in M_3 intersects infinitely many other algebraic curves coming from origamis.
