Hello. 
I've been looking at your maps for inspiration quite a few times, so I figured I should make a user and perhaps share something back.
Aside from looking at well-made maps, my interest in cartography is mainly within the realms of programming. That is, every once in a while I have some great fun toying around with creating map generators.
The day was spent making this
While I'm not completely satisfied with the colors, I like the end result enough to show you.
My goal was originally to create a terrain with mountain ranges and cliffs, something which most continuous noise based generators lack. First I thought of simulating plate tectonics, but after finding and reading laurimann's interesting thesis and playing with his demo, I felt the procedure was too time-consuming for my purposes. Trying to find a way to emulate real-life terrain with simplex noise, I eventually stumbled upon an interesting effect: piping a fractional brown motion space into itself as an added dimension! Given a 4D FBM f, compute the height like f(x,y,z,f(x,y,z,...)). In this program I "pipe" the noise once, but two or three times gives more more cliffs and more mountain ranges at a cost of computation and more swirly distortion.
Quick note about the controls:
RENDER renders with previous noise, SEED/RENDER renders with new noise
canvas->scale is a logarithmic scaling of the size, 512->1024->2048->...
canvas->steps_in_one size of chunks computed at once
general->piping reduces the smudgy distortion (0 is regular simplex noise fbm)
color->more->shadow adjust the amount of shading.
Not sure if this program is of any use to anybody, but I thought it could serve as a simple base map to be modified or maybe as inspiration.
What do you think?

Note: If you want to see the map on a sphere, just save it and add it as an image overlay in Google Earth
