Experimenting with creating a Dysonesque dungeon map in Photoshop. Of course, I'm not crazy-awesome like +Dyson Logos
and so rather than hand-draw the cross hatching, I use a texture (from the 2015 Profantasy Annual), layer effects, and an adjustment layer. Photoshop actually draws the hatching in real-time as I draw my rooms on the layer mask--looks pretty nifty to watch. About the only things that are hand-drawn are the cliff hatching and the natural stairs to the upper right. I used a hex grid instead of the typical square grid to be different, and because I like GURPS.
This is meant to be a fortified set of buildings set into an alcove on a cliff side, not unlike a Mesa Verde type cliff dwelling. I think the old Angus McBride Rolemaster covers are an inspiration to me--they've been so for quite a while.
