I played a bit of JSettlers2 (a Settlers of Catan rules implementation in Java) and was inspired to create a tile set for it.
Luckily the ant build script worked flawlessly, so I created some tiles from scratch, using GIMP’s noise function and my 4w3s0m3 pixel art skills.
You can download it here.
Unfortunately this only affects the 4-player map of JSettlers2 but if enough people want a 6-player map tileset as well, I will make one. Just leave a comment or email me at firstname.lastname@example.org.
