| Hi Alastair,
oh, once you have played with the "Replicate in Space" patch for a while, I am sure you will have lots of fun with it!
Try this one (can be rotated with the mouse cursor):

I'm positively sure I've never been able to get to the true potential of the Replicate in Space patch for one reason: a lack of Mathematical ability. All examples welcome in future.

I am sorry, I missed your point about drawing a parabola. Just to have another idea I did a compostition which draws a 2D math function with a GLSL shader patch containing a GLSL Grid patch. (Use the mouse to rotate the object). The magic happens in the vertex-shader of the GLSL shader: the vertex points gets moved around by a math function, in this case z = x * y. Maybe you can use this as a starting point to draw a parabola.

you can also use the "Replicate in Space" patch to draw an arch. I think it is one of the fastest ways, because the "iterations" are all done by simply transforming the view matrix in the GPU and doesn't need any recalculations of any QC patches.
Please note that you have to do a bit of math to calculate the line start and line end parameter based on the radius of the arch. I just guess some. (btw. in George's composition this math is also missing)

The interpolation all have built in curves, and one can build custom curves as well. Double also, the timelines patch can be used in the same way.
(I can't remember 100%, but I think that I used GL Tools plugin on the composition that was attached by James, and you can find that plugin (patch) at http://kineme.net ) -- George Toledo
