misc

This repository contains miscellaneous code from throughout my career.

I regularly add to this repo but do not support this code through github–use it at your own risk, and please don’t send feature requests or ask for help with it. Some of it was written while I was an undergraduate and may not compile on modern machines.

Some additional open source projects that I do actively support are:

• quadplay Javascript web-based fantasy video game console
• The G3D Innovation Engine C++ 3D graphics library
• Markdeep Document beautification tool
• iCompile Zero-configuration build system
• include.js Cross-domain, cross-browser HTML include tag
• codeheart.js Javascript 2D game library
