I sort of wish some of the European bike parking designs for high density, but secure, racks would make it over across the pond.
Some cool examples are at this website:

The main issue is that the bike parking is securely cemented in the ground (rather than held in by a couple scrawny bolts), thick (1-2+ inches at the minimum), heavy solid tubing (not cast off pipe) is used everywhere and are an integral part of the structure (not just brazed/soldered on.)
I still wish Kryptonite made their bicycle poles. It was a simple concept... just a thick solid pole set deep in concrete with a basketball-sized globe on the top welded on. This kept people from lifting locked bikes up and off, was resistant to all but the most determined cutting attacks, and looked very clean.
