Hi, Ken. Rendered at 800w by 600h, +am2 +a0.2, the following modification
to the camera and light source location make it even more obvious:
//camera { location < 0, -.5, -1.7> look_at 0}
camera { location < 0, -0.2, -0.01> look_at 0}
//light_source { <-10,10,-10> rgb 1}
light_source { <-10,-10,-10> rgb 1}
text { ttf "timrom.ttf" "BIG" .5,0
translate<-0.85, 0,0>
pigment{rgb 1}
}
text { ttf "timrom.ttf" "BUG" .5,0
translate<-1.05,-.67,0>
pigment{rgb 2}
}
background { rgb .35}
