Imagine a simple circle.  Now over top of this simple circle,
you have a smaller circle that 'orbits' along its perimeter.
This smaller circle is a gradient from transparent on the 
outside to opaque at its centre.

When this 'circle' orbits around the logo, it would
reveal the logo underneath, as a focused flashlight might
offer.  From this you get two easy variations -- one which
is almost exactly the same as your current version, except
with a 'circular' radar line.  For the second, you could try
keeping the entire logo darkened while revealing it as the
circle rotates around it, gradually letting the circle's 
trail fade back to the darker logo.  I'd give you a sketch,
but I am in a complete rush this morning, so I apologize.

I imagine you can figure it out from here though.  And who
knows, sometimes accidents are the best creative spark.

Great -- looking forwards to it!
