About themkat
  • Oslo, Norway
  • 83 designs
Love computers, math, sci-fi, classical art and more. I blog at themkat.net about those subjects (except classical art). My products range from computer inspired design, to older art that is color corrected and used in new ways. Use this site to share my art, and hopefully also see my growth. Many different types of art, software etc. I'm playing with :)
