The lcd object is very handy for drawing simple 2D graphics. This patch shows how you can plot a point in an x,y coordinate graph using lcd. The goal is to be able to plot any x,y coordinate pair for which the numbers lie between -1 and 1.

One way to superimpose 2D graphics over a video is to draw into a jit.lcd object and then use alpha masking to overlay the jit.lcd contents on top of the video image.
