Gromit lets you arbitrarily draw/annotate on your screen. This is awesome for annotating a screencast.

It doesn’t come with decent defaults. The README suggests this:

"red Pen" = PEN (size=7 color="red");
"blue Pen" = "red Pen" (color="blue");
"yellow Pen" = "red Pen" (color="yellow");
"Eraser" = ERASER (size = 75);
"green Marker" = RECOLOR (color = "Limegreen");
"Core Pointer" = "red Pen";
"Core Pointer"[SHIFT] = "blue Pen";
"Core Pointer"[CONTROL] = "yellow Pen";
"Core Pointer"[2] = "green Marker";
"Core Pointer"[Button3] = "Eraser";

It seems to work just fine.. it might warrant tweaking once I get to use it more often.
