Useless?? Hardly! Surely just doing Plot[...] and then Ctrl-clicking
is a lot easier for a beginner (e.g., a student using Mathematica) than
to deal with a Dynamic object.
On the other hand, and apart from the issue of what to do with
Ctrl-click when the graphics object is dynamically generated, there
would seem to be a design issue: Now, in 6.0, Ctrl-mouse-button-down is
the start of a zoom-in/zoom-out for a 3D graphic.
