This is more fantasy than sci-fi, but a guy on Kickstarter is going to build custom-painted 3D dungeon tiles! You can say how many you want, and whether you want unpainted ones to paint up yourself, or whether you will pay to have him pro-paint them up for you in a scheme of your choice!
I thought it was so awesome, I want to help spread the word, as he's only doing them for people that make pledges for the kickstarter, I think.
If I join in the pledging, I'm going to ask for one painted up in a sort of moldy old stone like something out of an ancient ruined temple in a Tomb Raider game (or something like that) so it could be used as ancient ruins for Star Wars jedi / sith skirmishes, or perhaps an abandoned ancient dwarven city full of goblins and lost dwarven treasures for some Lord of the Rings skirmishes, or who knows what else!
It's also designed to work for a 3D board, for the miniatures dungeon crawl game Super Dungeon Explore which is a japanese anima / console arcade game inspired board game - makes me think of Legend of Zelda or Pokemon or something :)
He's got photos of a prototype board, painted up in a fiery dungeon theme, and I think his stuff looks pretty awesome :)
Here's a link to his kickstarter page:
