EyeFloaterKalidoscope

You know when you are lying back, looking at the sky (or blank wall) with your eyes slightly unfocused and you see all the little microscopic "eye floaters" - the little bits of dead bacteria and whatever that are floating around in the liquid inside your eye? Well, EyeFloater is a collection of little microscopic colored shapes that you can have injected into your eye, so that now whenever you are bored you can lie back and watch your own kalidoscope show. This might go over well with the body modification crowd. Obviously you'd have to do a bit of tailoring to be sure to inject enough of them so that you would be able to see them, but not so many that it negatively affected your vision... Maybe you could have little smiley faces, hearts, flowers, peace signs, etc. Of course, the advertizing possibilities here are a little scary...
