Eric ( a geologist/muscian) wrote the orignal code (for grins) based on the academic work of Ken Musgrave (Mojoworld). Kia Krause and John Wilczak talked him into releasing it as Bryce. When Eric left MetaTools he made a deal with Kia to licenese his code with the provision he wouldn't release a Bryce-like program while Bryce was still around. When Corel, in their infinite wisdom, dumped the Mac version, it left Eric free to release this Mac only app. There's been some hints that now Corel/Vector is now trying to sue Eric.
