John, I have been hooked for a while. A good friend of mine was one of the guys that helped Artcam with path generation for Lithophanes. Loved the idea and now the availability of parts and information enabling us to use lasers really excites me. I often wonder what will be next and find some others efforts truly inspiring. Many of those others have posted in this thread. Marcel Beaudry's tiny cubes in cubes and a host of others come to mind. Tom Hubbin was working on 3d laser scanning before he passed. In a world where most refuse to think for themselves in order to accomplish trivial things, I come here and see the exact opposite. That is what I love. People who push to be above average and refuse to let the standard deter them from accomplishing their goals. Tweakie has always made my day in that respect. So, will I ever get to play with lasers.......... no idea but if I live long enough I'll have at least one of everything.
