Circuit City - kick-ass idea for a map for your BandB campaign

When I was a child I used to play with broken circuit boards and computer parts, using them as spaceships and cities. Yesterday I thought that pictures of PCBs can be used as great maps for the Bandits and Battlecruisers campaigns (and of course virtually any other sci-fi games). Here's an example (click to enlarge):

A - City's main sensor array
B - Heavy laser batteries
C - The marketplace
D - University and museum district
E - Military Compound (with military corp HQ)
F - Corporate Towers
G - Warehouse district
H - Residential area
I - Ship hangars (bordered with black)

If you like this idea, I'd love to see your maps!
