Bah! It's a dark exposure, but you'll get the idea of the side-mounted speakers that bring this backpack to life. It has yet to make a large public appearance... yet it has 'wowed' the crowds in all the smaller venues to date. Not that an Imperial Stormtrooper needs to work at making himself visible.
This backpack produces the same effect as a Harley Davidson motorcycle... you hear 'em coming from a mile away! (grin)
