I signal right turns by pointing right, which I think is pretty unambiguous. But I see people using the 'left arm out, hand up' signal for right turns, too.
I checked the League of American Bicyclists website just now, and was pleased to see that they've stepped into the current century at some point and now embrace the "point right to turn right" signal.
As much as I love archaic things, I don't want to trust my life to signals that require a history lesson to understand!
