When I manage to find some spare time, I try to get out and take a few pictures.  Photography has been an interest for about as long as I can remember (dating back at least to a toy camera that I'd carry around when I was three!).  You can see a few pictures from my time in Africa here.  I'd also recommend checking out the Miksang Society for Contemplative Photography.  They offer teachings based on Tibetan ideas about art.  It is certainly far from typical, but it is the most useful training I've ever done in terms of improving my ability to perceive. 

I'll add more material here as time and interest allows.
