Doing chalk in a straight-up fashion is fine and usually gets a strong response. But sometimes it's nice to add a little extra feature. Do you ever incorporate special effects like fire or smoke? Do you use a projector for adding animations or extra images to your drawings? How about a different, creative use of colored light from your light hood, color wheel, strobe, pin spots or rainbow prism?
If you are doing something different, odd or otherwise unique - let us know!
Creatively yours,
Kerry
