Ambrogio Cesa-Bianchi (not on Mastodon, as far as I know) has put online his #LaTeX #Beamer theme, which looks really useful for those who want to annotate text, figures, and tables using arrows (Tikz) and handwritten-like text (Augie).

The theme is available here: https://github.com/ambropo/JambroBeamerTheme and uses the GNU General Public License v3.0.
