Picture the scene:  Some guests are beginning to arrive at a reception. It’s a business event and many of the guests have never met. In walks a silhouette artist. It isn’t obvious that he’s any different from the other guests, but this is a guest with a unique talent.

He approaches a group and engages them in conversation. He produces a pair of scissors and – seemingly in seconds – cuts an astonishingly accurate portrait of one of them, holding it up to the light. Cries of amazement attract the attention of others, some of whom gather to see what’s going on.
