I like LaTeX and TikZ, they have a great educational potential. If you are italian look at my YouTube Channel made of screencapture of beamer presentations on mathematics. The code of my profile picture is:

\documentclass[tikz]{standalone}
\usetikzlibrary{calc}
\begin{document}
\begin{tikzpicture}
%hand
\filldraw[fill=white,draw=black,line width=8pt] (4.5,-10.5) coordinate (A) --  ++(0,3) arc (-55:-10:4.5) -- ++(0,9) arc (0:180:1)-- ++(0,-4.5) -- ++(-0.2,0) -- ++(0,6.5) arc (0:180:1)-- ++(0,-5.5) -- ++(-0.2,0)-- ++(0,6.5) arc (0:180:1)-- ++(0,-6.5) -- ++(-0.2,0)-- ++(0,5)arc (0:180:1)-- ++(0,-8.5) -- ++(-1.5,1.5)arc (40:220:1.2) -- ++(4.5,-4.85) -- +(0,-3)coordinate (B);
%arrow
\fill ($(A)!0.5!(B)$) ++(0,2) -- ++(60:3.5) -- ++(-1.5,0) -- ++(0,4.5) -- ++(-0.5,0) -- ++(0,-4.5) -- ++(-1.5,0) -- cycle;
\end{tikzpicture}
\end{document}
