LazyWeb, I invoke thee! (Since I do not have the ability to trackback, this is really just me yelling out to noone in particular…) Someone should somehow combine the Map of the Market with an actual aerial map of a city (or “market”, if you will). Use company addresses to plot their location on a map, and show the graphic representation of their stock price (ala the green/red color blocks in SmartMoney’s version) over the plot of their building/campus on the map.

I’m not sure how truly useful of an application this might be, but I think it would be interesting and I could see myself sucked into it for hours on end. It also might be interesting seeing how certain sectors of industry are clustered near each other (think semiconductors in Silicon Valley), and how that might make the whole city or area’s map look.
