What the **** is that?

One may wonder what the purple/blueish thing is i'm wearing on my arm.

Well i came across it when i did one of my laps on the SL Relay For Life sims. Loved it....i attached it....i never took it off. I don't know why but i'm keeping it on until the next SLRFL closing event. Maybe just to keep people reminded...no idea.
