Here is an example:

camera { location <-1.5,4.5,-10> look_at 0 angle 35 }
light_source { <10, 40, -50>, 1 }
plane { y, -2 pigment { checker rgb 1, rgb .5 } }

cylinder
{ -y*2, y*2, 2
  pigment
  { object
    { text { ttf "timrom.ttf", "POV-Ray", 2.1, 0 scale <.1,2,1> }
      pigment { rgb <1,.9,.8> }
      pigment { rgb <.8,.4,.1> }
    }
    warp { cylindrical }
    rotate y*160
  }
  finish { specular 1 }
}
