For me, the importance of the name of an art project should help the viewer relate to their life experiences.

In the end your want your art to speak to the person and the very best way to help them with that experience in my opinion is tying it to their life experiences or learned knowledge. Help them get past the perceptual defenses everyone puts up to stop the thousands of messages aimed at them throughout the day. If your art’s name ties into the persons life experiences it will help them see the message in your art – even if it is “art for art’s sake” only.
