I think the Flickr thing makes me more attentive to my visual environment. I like getting images of my local geo-space. I was interested by this, beneath the window of an antique shop, reflecting an earlier use of the building. [What would you do at a Temperance Bar - not buy a friend a drink, maybe?] So I'm looking out more, but at the same time working a lot onscreen feels like looking in more...and my eyes burn if I put in too many hours. It's looking as if even sending texts on my mobile is a strain, too. Still, apart from being blind as a bat from too much print-reading, my eyes are in good nick.
