What I'm working on right now.
A standalone application built with JavaFX. Eventually, I want this program to be a GUI-based toolkit for Game Masters running combats in Tabletop Roleplaying Games (such as Dungeons & Dragons). Currently, the program tracks turn order based on initiative and allows the user to store notes about each creature in the combat. However, I plan to add many additional helpful features, including smooth handling of initiative collisions, status effect tracking, and dynamic UI for storing creature-specific data (such as hit points, ability charges, and spell slots).
A digital toy built in the Perlenspiel engine for Javascript. Differently colored blocks fall in different directions. You can shake them around, watch them collide with each other, and send them falling into an endless void. Currently, I am working on polishing the toy to make it as fun as possible.
