You wouldn't know it from most of my work, but looking at the thread so far it looks like I might have been learning Bryce the longest (note I said "learning," in the present tense; people who have used it for a much shorter period of time have taught me a lot). I bought KPT Bryce 1.0 when it first came out as a Mac-only version. Ah, the days of rendering a chrome ball over water on a 20 MHz (yes, twenty) Mac IIsi with 17 whopping megs of RAM. My learning method has mostly been 10 years or so of scattershot experimentation. Maybe I should check out that "Real World Bryce" book! :)
