Funny that this topic has come up. In my younger years I never worried about the fan getting in the way of my fingers/hands, but now I am flat out afraid of the darn thing. I've seen chrome and mine is black, and it seems to me they're both nearly invisible. Has any one got any solution? I know a shroud would help, but maybe some paint scheme that could be readily seen? Maybe a spiral design on the blades to appear as though it's moving?
