Free software

Demakein: Wind instrument design software. Design an instrument than produce shapes for 3D-printing or CNC-milling.

ghostsurn: eye candy. Assembles pixels or tiles into interesting patterns.

Ghost Diagrams: eye candy. Assembles tiles into interesting patterns. Predecessor of ghostsurn.

Synaesthesia: music visualizer. You can distinguish several individual instruments at once by its display.

Nesoni: Bacterial high-throughput sequencing analysis.

Aether: wikiesque Python CGI-script for managing web-pages and web-logs. I wrote it mainly in order to manage this site. Create, edit, move and delete pages, attach files, create web-logs (with accompanying Atom feeds), all from your browser. Supports unicode. Very easy to install.

Bonk: audio compression. Lossy and lossless. A very simple piece of software, the source code is only 32kb, but it gets compression ratios similar to those of FLAC and MP3. Interesting if you're into compression, otherwise use OGG and FLAC.

PyMML: a Python library for MML-style statistical estimation, including automatic classification of data.

PyLevy: a small Python library for calculation and fitting of Levy stable distributions.

yaedit: a minimal programmer's editor, uses PyGTK and gtkSourceView.

The Problem of Good: A platform game written in Python, demonstrating a theory of how goodness could comes about in an uncaring universe.

GIMP plug-ins:

Resynthesizer: a plug-in for texture synthesis, texture transfer, and donkey removal. As a bonus, you get scripts for deleting a selected area by synthesizing surrounding texture over the top of it, and for enlarging an image while maintaining its sharpness.

TextureOps: cut and paste images together without munging the texture. Make seamless tilable images (better than the Gimp's built in Make Seamless filter). Synthesize a piece of texture of arbitrary size from a sample.
