Here you can find some of my scientific projects.

My collection of free software and patches for DOS, Windows and Geos.
Besides some scientific programs (see above) that I can distribute, these are mostly small tools or games that I did long ago.
The second half covers a couple of mods and patches for some PC games.

Web Based

Web based software that runs in the browser window or by e-mail.
These are mostly proof of concept of what can be done with standard browser stuff (Javascript) without having to resort to Flash or CGI.


Explore my creative side.

A container for everything else.
Mostly a retirement castle for older websites I created that aren't maintained anymore.


Places on the net that are of interest.
A collection of not so well known web-pages that are useful to know.


This is the impressum section.
