Research and other work
Here is some of my work:

• Joint paper with B.Bischof, D.N.Yetter: On a Basis for the Framed Link Vector Space Spanned by Chord Diagrams , accepted for publication in Journal of Knot Theory and Ramifications.
  See Preprint at ArXiv.
• Chord Diagrams, a Java/Mathematica software for that paper;
• NvTrees, n-dimensional Thompson groups calculator (Java Applet and Standalone);
• Evolutes, a program that draws involutes, evolutes an osculating circles for a given curve.
• If you are into computational geometry, you might like the Delaunay triangulation applet, which illustrates the algorithm of computing it by a lift to paraboloid.
• If you need to visualize the Newton polyhedron of a polynomial and count lattice points inside it, Newton Polytope applet does precisely that.

Other
Listen to my electronic music, see my photographs, read my survey of history of elctronic music (get a print version: [PDF] with less typos). See a cool Processing-JS demo, and Cross-eye pseudo-3D demo. Try the arcball interface implemented in Javascript (again, with Processing/JS). If you have a webcam, play with the Webcam Scanner Camera.
