Bits n Bobs

I want to create two characters for this illustration, one on the left and one on the right. Both have to be related to computers or the mediacity itself, here are some of my ideas....
. mouse
. pen drive
. keys on keyboard
. printers
. rubber
. pencil
. sketchbook
. Building itself
. monitor
. usb cable
. graphic tablet
. webcam

Its difficult to come up with items and then transform them into characters but im slowly beggining to bring emotion and character into my illustrations.
