A lot of people would really like a snow map. Herb's thread covers most of the points for having a terrestrial map, and I really hope OldPotato's map gets finished. That said, this is my own proposal for one. I've made a forum post about it here to gather opinions
The quad shape

This design features a whole four domes.
The domes are (in clockwise order) bridge/sec, engineering, civilian, and medsci.
Plotted it out with two airbridges per connection, possibly so that pipes and wires could run between the two and be "shielded".
Even if one airbridge is destroyed/blocked off, you can go the long way around. Or just walk outside idk.
Sitting in the centre is a snow garden. Could have penguins or something.
