I came across this webpage. Partly attracted to it as it makes a "crash proof rig" for phones. The video starts with the very likeable man dropping his SLR camera from 5ft in the "crash proof " rig. Gets your attention! http://publiclab.org/wiki/balloon-mappinghttp://publiclab.org/wiki/pet-bottle-rubber-band-rig
Could have done with on Dieppe beach!! The rig and camera were fine thanks to the legs of the BEAK taking the impact. This is a different and cheaper solution.
The map knitter part of it is to put high quality photos on Google satellite maps. Follow their links to that.
