Back again. I've been asked to nominate a particularly pleasing tool or facility on the Flickr photo sharing site. It reminded me of the Dali Lama's response when he was recently asked the secret of happiness; "I don't know". There's a huge range of interesting, maybe even useful, tools there. Have a look for yourself at:

Warning: the Flickr site can be a great time-waster.
