The USGS has published this archive as a single ArcGIS Image Service called LandsatLook. The prototype described in this posting uses this service in an HTML5 web mapping application.
While the map view is perfect to identify an area of interest, it is not so useful for sorting through hundreds or thousands of overlapping images. This prototypes uses a control developed by LobsterPot called the PivotViewer to present a sortable collection of imagery. Using the map and pivotviewer together, the presenter in the video above was able to quickly find and download a recent cloud-free image of London.
