Downloaded Harlan's mods, and am using those pretty extensively in my game, but a few of the icons weren't to my liking...
So I changed them. I give you:
New clay, new tobacco, and new oasis.
The clay is a compilation/lift from Caesar III and actually looks like large loaves of clay. The tobacoo resource was a big ugly pipe - blech. Now it's an actual tobacco plant. And the oasis is a derivative of Harlan's, with an added tree and a blue pool. I don't like the pool the way it is, so someone with more skill than me please improve on it...
Also included are the shadows.
Feel free to play with these or redstribute/incorporate them in your own mods...
