Magnum Mania!

How hard is it to create a moving signature like Zebra3 has, but using Magnum footage - i.e. Magnum smiling, raisng his eyebrows, pulling the trigger........etc.? Probably out of my league, but it would be neat to see one us tech savvy users apply one.

Trying googling something like animated forum banner or animated forum signature. There will be a free program available somewhere that will do it for you.
