Hi, I am trying to achieve this effect from transformer 1, where the allsparks cube had this “wire-frame glow” then slowly transforming into a small cube. The only way I can thing off is to use a box with points, copied box on each points and scale them slightly, allowing light inside to sip through the gaps. Anyone had any idea and help me out? Thank you.

Here is a image of the effect: http://img7.imageshack.us/img7/192/cubelinehighlight.png [img7.imageshack.us]

Thank You.

you could do that, or composite a wireframe render of a large cube with as many divisions as you want, rather than make a light shine from within the box. Might just be a faster route.
As for the animation, you'll probably have to do the copy SOP method…

Cheers
