I'm interested in building peripheral vision

we need a button to address a friend and go "hey", and that's it. just a nod, but it should be groupy already so you can nod to everyone around you. at its most basic, i want to be able to share a stroke. it should be a little bulb in the corner of your screen, and if you cursor-hover over it it lights up every so slightly on the screens of all your friends (and fades slightly on theirs over the next hour).
