Highlight mouse for screencasts without disturbing workflow

For making documentation/tutorial videos, I need to highlight the mouse, for example with a yellow translucent corona around it: The marker should be active when clicking and moving, but if it's on all the time, that's just as fine. It can obscure the view on what is behind it to some degree but it may not disable being able to click what is behind it or take focus away from windows. Compiz seems like a thing of the past, find-cursor isn't tied to any actions (clicks/movements) and blocks interaction (while it's drawing, you can't click "through" it) and key-mon doesn't draw correctly, disables interaction as well and is generally buggy when it comes to the mouse highlighter, at least with a tiling window manager. I'm using Arch Linux and awesome wm. Thanks!
