86 is cool. the "S" is kind of hidden by the road. what if we: 1) made one of the stripes in the road red?....or 2) left the font colors the same and added colors to the different buildings to represent different levels of measurement?
95/96: I like the colored buildings....now that I'm looking at that red stripe in the road, it really looks like Barak Obama's political logo...so maybe we revert back to the two-tone blue you had before or a grey road (or maybe even a grey/green combo).
