I'm taking up the challenge posted by Stephen Curry on the Nature Network to give a quick illustration of my working environment.
I love the curved desk (thanks, Ikea) and also having a window looking out on green stuff. A small prize to the first person who can work out what my favourite painting is (there's a print above and to the right of the monitors).
Unlike Stephen, there is no stereo - I do have a lot of music on the computer, but hardly ever listen to it when working. I have to be doing something really dull and mechanical (my accounts, say) before I can have music on without it being a distraction.
The books go with the job, I guess (though more than half of those on view are fiction). I tend to have a couple of shelves of books on the subject I'm writing about at the moment, as well as the usual references (though my favourite, the OED, I use online thanks to our local library).
The row of books at the top right are my 'I should throw them away, but...' books - they are spare copies of translations that I keep on the off-chance I will one day meet someone who is interested in a Czech book on creativity (say). This has once paid off, when I did some work with the University of Westminster with a group of Chinese speakers and managed to offload all my spare books translated into Chinese, but so far the rest are reluctant to shift.
