\section{Chalk Studio} This is the tool I use to generate chalk drawings/writing/LaTeX for my presentations. Everything exports as a transparent PNG, so it drops straight onto a slide. Math is rendered in LaTeX form, e.g. $\R^n$, $\norm{x}$, $\frac{-b\pm\sqrt{b^2-4ac}}{2a}$. You may also adjust the size, grain, and "wobblyness" to give it a more handwriting feel. Note the handwriting is randomly generated, and is prone to look bad.
