Right, so here we go for real now. The "less known hexcrawl" is of course the science fiction hexcrawl. Case in point being Traveller, which used (still uses, really) numbered hexes to map the universe. Players would use their ship to travel from one system to another, conducting trade and so on. Random tables determined if they ran into pirates or other spaceships. Systems were not very detailed; they used a string of hexadecimal numbers to describe the main world. While a primitive method, this did allow the Traveller authors to map out vast areas of space.
And that way, the Traveller setting really had the same problems any other hexcrawl had - no detail, no action, no story except for what players and their GM improvised based on the rules. The few game modules that were written and published were often set on systems at opposite ends of the setting, but some modules detailed smaller regions of space - such as 10x8 parsec sized subsectors; or an arbitrary number of neighbouring systems for a scenario in which the characters went on a treasure hunt.
About the image itself: The background is temporary (I hope). The placement of systems follows a modified version of the Mongoose Traveller SRD world creation rules (which I am making up as I work on the map). Time constraints probably (almost certainly) mean that I will not be able to map every hex on this map, let alone roll up stats for all systems... There are, after all, about 4000 hexes on this map. Original image is A1 (84x59cm), so I will be posting severely scaled down versions while I work on it.
