The additional information now is text because I didn't find a way to
merge the additional arrows, it is just a stop gap, and on the
directional arrows I'm only doing 16 directions, not all 360 degrees,
but when I figure out how to add more layers then I'll want to add the
last 3 directions and a prevailing direction, so I don't want to be
limited. Besides it isn't as if the machine is working hard on anything
else it does.
But I like the idea, that if the same combination is asked for again
that it can just read the image from the drive and display it rather
than regenerate it. Do you have sample code that can do that?
