HI Mat,

You can tackle this a number of ways.  The route I'd take would be to
create a static sized box using an osg::Geometry (see the osggeometyr
example) then use a vertex shader to modify the vertex values.  Have a
look at the osghaders for how to set up shaders - this example
includes a code path which animates use vertex shaders.
