This is a mini-sandbox hexmap for an RPG campaign. Created entirely in GIMP, save for the Hex overlay, which was taken from a public domain source, opened in GIMP and to which I then added the hex-numbers.
I created the hex icons myself. The dragon, featured on the icon in hex 0903, originally was from a PD picture, but after major shrinking and the necessary, subsequent touching up, looks nothing like the original picture (and just barely looks like a dragon. :P )
