For many years I have been working on various projects relating to data, computer software, operating systems, art, design, photography, psephology, mathematics, and economics.

Sometimes this work is for others, sometimes for me; sometimes its public, sometimes its private; sometimes its serious, and sometimes its rather frivolous.

This page signposts my publicly available work which may be of interest to curious visitors.


Here is a list of projects on the web that I have been responsible for creating. Select a project name to go to its website.

mtCellEdit (2008-2017)

This began as a simple spreadsheet program and then became much more as I added other programs and libraries to explore my ideas.

A minimal widget toolkit for SDL.

A 6502 disassembler.
