These U.S. senators are (on) crackers

My 14-year-old pointed me to the cool work of artist Christian Faur. I see Mark featured his crayon portrait pieces on Boing Boing in the past but not pieces using his more recent medium of soda crackers!
Prior to the midterm elections, he laser-etched all the (then-current) U.S. senators on crackers (Is the medium the message?):

Thanks, SJ!
