Spatial analysis researcher Oliver O'Brien has produced this interesting live map that visualises current hire bike docking station use.
It's updated in real time from TfL data and shows if docking stations are full (red) empty (blue) or the half-full ideal (purple).
It vividly illustrates the tidal flows of commuter use through the day. Central stands fill up (and frustratingly offering you nowhere to dock) and peripheral ones empty (frustratingly offering you no bike to take out) with the process reversing in the evening. (Thanks to Werner for alerting me to this.)
Oliver's blog Suprageography has other examples of visualisation stuff he's been working on, from Mancunian history to London tube use.
