The idea of the maps is to NOT be stuck within the confines of an aperture science lab. Outside, and where things dont make lots of sense. Different style of mapping, putting the player in different portal-based puzzles.
Here's a few screenshots:
Map 1:




Map 2:

Map 2 has more to it, but most of it is pretty dark, or very incomplete.
I dont think I'll ever get back to these maps, so if there's anybody out there willing to finish 'em for me, let me know. Make sure to point out what you've made already, so I can choose a good mapper to finish them up 
Update:
Play map 1 here: dload.php?action=file&file_id=237

awesome!


. I realize you probably didnt even play my map, but I think its cool to see more rotating
