Well.... To my right there is my trusty computer, my mouse, an empty bag of skittles, a drawing tablet, then on the ground there's a TV screen. Then in front of me is a clock thing, my monitor, and lots of TWIX remnants.
And to the left(to the left //brick'd) there's cans of compressed air, my mom's CPU monitor, a bag of crackers, a plastic snake, lots of cords with USBs, some hard drive things, mail, plastic bags, a heavy backpack....
Lots of useless crap. Best I could do is probably the bags to wrap around zombie heads, TWIX to distract, the TV and backpack as projectiles/bash-ins, and probaby the art tablet as a shield, but maybe Mom's massive CPU monitor would be better. Then the compressed air as grenades or something.
