We haven't been doing this regularly -- I think there was one announcement on comp.graphics and comp.sys.sgi. This is a good point; we should start a geomview users' mailing list. We wouldn't want to broadcast to some large group every time we release a new gadget, but it'd make sense for a geomview interest group list. > 2) Do you know if there's an interface to Mathematica in the works > anywhere?

We've talked about a couple of things along this line -- "constrained" motion along just the display axes (so e.g. an approximate horizontal drag would be taken as exactly horizontal), and motion about the object's own axes, so (say) a pure horizontal motion would amount to rotation about the object's own Y axis, no matter how that was oriented on the screen. Would that do? Both would be pretty easy to implement; the problem would be choosing a convenient way to specify when you wanted them to apply. Thanks for your comments & for the "-stdin" script!
