Being a Ceramics teacher you know I have to include some clay for you. :)  These two cups, titled Boys, are by Tammy Marinuzzi.  She is a contemporary ceramic artist, as well as a teacher, who is inspired by peoples' facial expressions, body language and human imperfections.  I have included her here because when she builds she actually likes for the seams or "transitions" from one clay piece to the next to show on the outside.  Normally you would blend these in, but she chooses to leave them showing as a way to get at that idea of imperfection that she likes.  Can you see them?  Can you see how she incorporates the seams into the overall design of her pieces?  I think they have a unique charm to them.
