Here are some 24 hour comics by artists I've worked with. I wanted to post these links for awhile, but I was waiting to see if Brock Rizy or Brent Schoonover would make their 24 hour comic available online. (Daniel Warner, have you done one?) Diana and Paul, both amaze me with their talent.

Diana Nock, UrbEX
Paul Milligan, God of Rock and The God of Rock Strikes Back
