I would like to add on my beamer slides something that simulate as if I had been drawing a comment by hand. This would circle, come on top of text or formulas, and allows to insert text. Ideally, I could use this with the beamer overlay specification, i.e. add it only in a second step. See example below.
Is there anything that could bring me somewhere close to that?
\documentclass[english]{beamer}
\usepackage{babel}
\begin{document}
\begin{frame}{Make Titles Informative. }
Iintroduce here two theorems:
\begin{theorem}
Algebra
1+2=3
\end{theorem}
\begin{corollary}
2+1=3
\end{corollary}
\end{frame}
\end{document}
Thanks!
