ppict-slide-grid
This package provides a function that sets up a grid on ppict-based slides that can be handy for judging the coordinates to use for placing slide elements.
To use, just put the following at the top of your slideshow:
(require ppict-slide-grid)
(set-grid-base-pict!)
Make sure to disable it for your actual talk!
