Apocalypse's logs are really cool. I don't have Transtellar in my mod; the only corporation straight from Apocalypse is Megapol, which is still "to do" though.
I wanted to have an external wall with a logo, but I think I'm done with crafts for now, I hit the MCDs limit (also logos on curved walls are difficult, since you have so few pixels). The whole craft tileset is very modular now, so I squeezed out some room for more MCDs, but I'm waiting in case the playtesting tells that some tiles are needed (I suspect I'll need an external stair-ramp for example).
