A good audio book makes for excellent background sound for any sort of art, at least in my experience.
Try sculpting with materials other than clay like wire. I have also had a lot of luck with a paper clay that Michaels sells that is air dry. Needle felting would be another good non-sewing machine non-oven required sculpting method. You can get needles on Amazon or eBay for pretty cheap and you can get wool or synthetic yarns to create felting fluff from at Michaels or Hobby Lobby or any other shop that sells yarn.
