Over time I have developed a few software tools that are freely available for download. In particular, there are two that people often ask for.

  • Dagstuhl Timer: Processing code for helping with managing a series of short presentations (such as 2 minute introductions at the beginning of a Dagstuhl Seminar), written with Jason Dykes.
  • Characteristic shapes: Non-convex hulls for sets of points in the plane (Duckham et al., 2008).
