Very, very nice, Andy. I like it! You captured both the technique and the spirit of this sort of map wonderfully. Some of the filtering is a bit heavy (but only 10% or so), and the lighting is a bit too much for my eye, but those things are insignificant. Great going!

So, did you find improvements to my method? Also, the border curls are intriguing; how did you achieve them?

Hats off to you, sir. Well done!
