We need 3 variations of 30 tessellated sets just like in the example image. Please notice that the example that the edges are NOT square. They are jagged and that's really important to ensure that when everything is connected it gives some nice variations. The example is perfect, but please do not copy the example. It's for inspiration only. You can use alternative colors and feel free to be a bit creative.
If you don't know what a tessellated image is - please ask
The terrain should represent at least the following:
tar (like in the example) or ooze
The remaining sets are creative license. It could be alien landscape, tech or really your choice. The end product can be vector or bitmap. I imagine that bitmap will likely be easier.
Here's an example list of the 15 Kinds of terrain - To save time by just having a light and dark variant that reflects like day/nite.
These are only recommendations - Bonus points to designers who come up with creative stuff. It's a foreign world and nothing says the grass must be green.
Dirt (Earth - brown)
Dirt (Mars - orange/red)
Dirt (any color)
Tar or Ooze
Stone (probably gray, but other colors welcome)
Snow dessert / ice
Blue grass (alien lands)
Rusty red grass (alien lands)
Marble (color is designers choice)
Gray Metal flooring (future tech)
