I spend most of my free time tinkering either with Xojo apps/libraries or small technical projects. Over the years I’ve done quite a few. On this page I'll try to list the more interesting ones.
An object-oriented, embeddable, dynamic scripting language written entirely in Xojo implemented with a fast stack-based bytecode virtual machine.
A complete Xojo port of the excellent Box2D rigid body physics engine.
A Xojo module that adds lots of methods for dealing with strings.
