Terragen hasn't been a one man (programmer) show for a long time.
But Matt's still the mastermind behind the heart and soul of Terragen, its rendering engine and procedural systems. Jo spends a lot of time making it easier for you guys to actually access and easily use that stuff.
But I digress. I love seeing the variety of results that come out of these programs, in fact fractal software (like Fractint, in the early days) were one of the things that got me interested in computer graphics in the first place. Speaking of Mandelbulber stuff, I recently ran across some really cool, more realistic (as in "what if these shapes were real-world sculptures?") renderings, and I really liked them. Check it out:
