Random collection of others tools I've developed for research, teaching, or just for fun.
A typewriter-style, bare-bones HTML-MathJax previewer, with very generous output space and large fonts, and few distracting elements. Intended to be used for teaching (either in person for large lecture halls, via projectors; or via Zoom via screen share), or as a quick scratch board for mathematical discussions and brainstorming. It is portable by design; and can be installed as a progressive web application for off-line usage. Source code available on Gitlab.
