This is cool. Could probably do the exact same thing with the twist deformation in PSP. It could come in handy if someone ever wanted to model the impeller part of a centrifugal pump. Or blading on a radial flow turbine. Same is true for centrifugal compressors/blowers/fans, but they're just really another type of cent-pump. Heh... Also I see that A.S. has something in the works for the crest of a wave. Which will be cool. Now people will be wanting to use that boolean surfboard model that came with Bryce. Heheh... Gotta admit, terrains always were the most flexible feature in Bryce. It's all in how you go about using them. :)
