wow check out http://www.flickrvision.com/
I've known abaout twittervision for a while and whilst I check it out from time to time not being a huge twitter convert have found it a little banal.
But flickrvision really adds a new dimension to flickr, it shows flashes all over the world and sometimes these photos really are of true brilliance.
I dont know what it is about Flickr but for some reason it seems to really attract true photographers rather than just the average snap happy photo.
Being able to see these shots tied to a geogrpahical area real time (albeit it displayed real time and not actual photograph real time) is a new level of functionality for flickr.
