Short version: how to view the geolocated molecules:

• install the Layar browser
• be in Cambridge
• look for the "cambridgemolecules" or "Cambridge Molecules" layer

This is how I setup the backend for the geolocated molecules, using Hoppala to provide hosting and editing for a Layar layer. Layar indexes Points of Interest (POIs) with associated information and URIs. These can then be picked up by the Layar browser on a mobile device, in order to create the 3D overlay on reality. However, Layar doesn't host the files itself; one option is to use Hoppala, which both hosts and allows for easy editing of POIs and metadata.

This is a description of the conversion process for importing molecular structures into Layar: converting the PDB files into the format Layar uses, importing these files into Hoppala and placing them within a layer.

This is a quick mashup, to create an augmented reality layer of molecular models for the PMR2011 Hackfest in Cambridge.
