Chris:
Perhaps you could do something with FACES carved in golf balls. I've long held that the humble golf ball offers a perfect medium for practicing human expression. The human face is a wonderfully complex and varied thing and we are hard-wired from birth to read very subtle changes in its componentry. It is said that some 90% of all communication is non-verbal and facial expression plays a big part here.
Here are a few examples of 'expression exercises' using ordinary golf balls with half the cover removed. The faces are then carved into the material that is already inside the ball. As far as I know there is no way of know what colour you will be dealing with until you have the cover off.







I've done a couple of simple WIP's for various forum on this topic, but never for the print media. I have most of the photos neccessary already on file.
I'd be interested in hearing from you if you think this might be of interest to your readers.
