Just a little shift on your post but,,, It is addictive. It's a blast to do when things are behaving. Just as it's a tremendous hobby and therapy for a lot of people. It is taking over a lot of media and business practices. It will get much bigger... But, I'm not altogether sure if spending massive hours in front of a screen is healthy. It produces its own stresses. So long as you use it in small doses things should be fine. It's just that more and more life involves a pc. Email, shopping, reviews, info searches, even work. Better minds will decide what effect it has on creative people with its "no real tangible" materials pallette. Look at it this way... If you had a twin and you visually erased the pc from the desk he/she sat at, how long would you allow your twin(you) to sit in a frozen state staring straight ahead? I just don't think the human body was designed to do this for extended periods... Yeah,, stretch, jog if you can, change rooms once in a while. Maybe in a few years the "process" of rendering will speed up and even be more intuitive (voice commands). Till then, listen to that aching wrist. Now, I should read my own words...
