It can show actual videos using the Sixel protocol. You already have terminals that support it too. Just run `xterm -ti 340`. In that terminal, run an application such as Gnuplot:

    gnuplot -e "set terminal sixelgd;set hidden3d;set view 62, 30, 1.1, 1.2;set samples 50, 50;set isosamples 51;set contour base;set cntrparam order 8;set cntrparam bspline;splot [-12:12.01] [-12:12.01] 2*sin(sqrt(x**2+y**2)) / sqrt(x**2+y**2)+x/53+y/37"
