I haven't had any free time to work on it. I like that last C option.
I don't know if it would help any, but it might be nice to have lines in the water like a globe has (longitude and lattitude) to better show how the sea is round.
Then again, that might not look so good.
As-is, I like C, but think the "2007" is too small to show up properly. Easy enough to fix.
