I don't know. I plugged in my iPhone to recharge it - and found this mystery picture there - clearly it was taken - well, where? How? Is it the inside of my bag, of a coat pocket, or what? I really like this sense of the accidental, of light spilling into the apparatus uninvited: it belongs, in some oblique way, to my latest enthusiasm for Slow Photography (pin-holes, here I come) and for the idea of taking, in one way or the other, an image of time passing. The great thing about this image is that I don't know what time it was.
