These web pages were designed by external link Malcolm MacIver and Johannes Zimmer. The style sheets build on those external link Michael Bader developed for the web pages of the external link Master's Course in Computational Science and Engineering at the external link Technische Universität München. Johannes Zimmer adapted them to our needs. Malcolm MacIver created the navigation bar; we used external link ColorImpact to choose four matching colors. Since the pages do not use frames, we experienced difficulties in defining the proper scrolling behavior under Internet Explorer. We used Eric Bednarz' external link trick to obtain fixed positioning for Internet Explorer. Eric Wing wrote a nifty script that generates an image of an email address based on information passed through an URL.
