I'm a Computer Technician from Valencia (Spain), addicted to raytracing. All this started as an "innocent" secondary hobby, and now I expend almost all my free time typing POV-Ray scenes.
I have first heard of raytracing when I was hooked doing stereograms, around 1994. Apparently, something called POV-Ray served to create the gray-scale images needed for stereograms. Then I remembered having such program on a CD... I searched trough my CD pile, and finally found it.
Well, as you can figure, I never more returned to do stereograms... but it still bothers me to have had POV-Ray 2.0 for almost two years on the shelve, just in front of me, without knowing what I was missing... I could have had now much more experience! :(
At that moment, I had another "main" hobby: making music via MIDI. This is also a very addictive hobby, and it took me some years to progressively abandon music in favor of raytracing. It seemed that I was doing it better and better with POV, while my musical skills were stalled. Indeed, raytracing with POV-Ray was much more cheaper and, the most important, more satisfying for me. So, I finally abandoned the musical hobby some years ago, and all my free time is now for POV-Ray.
