Accidental abstract

I met one of the guys from the music group this afternoon for coffee and chat. Afterwards I continued on in to to town, parking the car in my favourite car park (on Sean McDermott Street).

I've recently got into the habit of using the iPhone to record where I've left the car under these circumstances. Having done that, I must have accidentally activated the shutter again as I was putting the phone back into my pocket. It was only when I uploaded to the computer that I discovered the accidental abstract result.
