One of several possibilities:
Use the Grid Texture on Luminosity to create a narrow vertical
glint (or sheen) on the logo face surface.
To get a narrow vertical glint:
Set the Texture Falloff to a rather high value in the X axis,
(200%, for example, to get a 1 meter wide glint, assuming a 100%
Texture Value.)
World Coords must be ON.
Texture Size is irrelevant.
Texture Value should be at least 100%, or more for a brighter glint.
Line Thickness must be 1.0.
Then parent everything in the scene to a new null object; camera,
lights, objects... everything.
Bank the null to obtain the glint angle desired, and move the
null off along the X axis so that the glint is beyond the end of the
logo.
When the time comes for the glint to travel across the logo, move
the null along the X axis, and the glint, tied to the world coords,
will pass over the logo, sheen-like. (Actually the logo passes over
the glint, but who's counting. :)
The thing I like about this method is that you have more
immediate control over the width, brightness, angle, etc. of the
glint than by using lights, or using a reflection map or other image
that would require repainting to change these attributes.
Also, unlike an image, Grid doesn't get blocky pixel disease.
