Asaph is a tool for Christian music groups and worship leaders for managing song databases. Features include song searching, printing song lead sheets with or without chord markings, and generating presentations for use in group worship. It is open-source and written in Java, so it should run on most common platforms, including Mac OS X, Linux, and Windows.

I am the primary developer of Asaph. The project has been stalled for a couple years, since I've been very busy with my other projects. I do (badly) want to get back to it, but haven't had the opportunity.

FileTyper is a popular shareware file and folder attribute editor for the Apple Macintosh. It was one of the pioneer "drop-box" applications, and its power, speed and simplicity have drawn rave reviews since its first release in 1991. Distributed with FileTyper is MakeAutoTyper, a widely-used utility for creating customized automatic changers called "AutoTypers".

I am the developer of FileTyper. This project is on the back burner right now, and has not been updated for several years, although there is the possibility that I may pick it up later if I become active in Mac OS software development again.

The GLOW Toolkit is a cross-platform user interface framework for building interactive applications using OpenGL or similar APIs. It provides an object-oriented API and an extensible library of cross-platform widgets. It is open-source and written in C++.

I am the primary developer of GLOW. This project is on the back burner right now, and has not been updated for several years, although there is the possibility that I may pick it up later if I become active in 3D graphics again.

Turtle Tracks is a modern implementation of the Logo programming language, developed using Java. It includes an interactive interpreter that can be run as a standalone application or an applet. The runtime is also extensible and embeddable. It is open-source and written in Java, so it should run on most common platforms, including Mac OS X, Linux, Windows, and Solaris.

I am the primary developer of Turtle Tracks. This project is on the back burner right now, and has not been updated for some time. I do not know whether I will pick it up again in the future.
