horrible claw-like hand gestures.

I've been practicing my DRP presentation. Since the guy suggested we use a projector or something so I don't have to write everything on the board [which is really really time-consuming and we're limited on time], I don't have to worry about what I'm doing. But I find that I make horrible claw-like hand gestures when I'm not holding onto a piece of chalk. It's been so long since I've had to make a speech where I wasn't constantly writing on the board. I had to take classes in high school! I did extemporaneous speaking and debate! I know how to talk in public. But it doesn't involve being a velociraptor...
