| OvalDock | Creates a customizable dock around your mouse cursor. Think of it vaguely like the start menu, but rounder. | GitHub |
| AutoMark | A proof of concept for automatically marking scanned homework assignments. | GitHub |
| Glance | An old android app that I wrote for displaying the time and notifications when taking your phone out of your pocket. This was back when android did not have this feature. | GitHub |
| stallings-folding | A fun program for graphically and interactively perform Stallings' folding procedure. Every finitely-generated subgroup of a free group is still a free group, and this lets you find the free generators starting from an arbitrary set of generators. | GitHub |
