The advantage is exactly that, save weight. But you can't just cut holes in the metal to lighten it, you must dimple it to give it back it's ridgidity (sp*)

Also some people cut holes in members to add cross tubes to add strength to a member so that it will not fold/compress. Not sure how to explain this except you ever take a carboard box and unfold the flaps and set it on the ground on its side? It has the tendency to flop and fold flat. Now if you ran a tube from one side to the other it would stay put.

There are pics everywhere but I think this one give a good level view of the holes & dimpling.

Plus the shit just looks cool!

You can get versions that use a bolt to squeeze the dimple into the material or versions that fit in a press or press brake. Certian materials will crack before they dimple, mainly harder steels, Ti, some t-6 Al.
