Art has to move you and design does not, unless it's a good design for a bus.

In this quote, the speaker is making a distinction between art and design. Art is meant to emotionally move the viewer in some way. It can evoke many different types of emotion, from joy to sorrow. Design, on the other hand, does not typically evoke emotion unless it is a particularly good design, such as a well-designed bus. Good design can still be appreciated for its functional purpose and aesthetic appeal, but it does not typically invoke an emotional response.
