One of the best things about SH was the corridors and how you fit them together to create your own missions.

I'm doing a visio program so I can just drag and drop these tiles into place and print out a new mission layout once the game is released. I think this willl be a great tool for creating your own missions with out drawing it out and finding you only had 7 corners not the 8 you actually need or some such like.

But I'm thinking it's probably not the best way to create the programme, anyone got a better idea what could be used?
