  That isn't a circle, is it? ;)

  I won't try to explain the theoretical background behind the sin() and
cos() functions, but I'm sure you'll figure out how they work with this
example:

// This assumes 'clock' gets values between 0 and 1 (as is the default):
#declare Angle = clock*2*pi;
#declare CameraLocation = <-12*sin(Angle), 0, -13*cos(Angle)>;

-- 
#macro N(D)#if(D>99)cylinder{M()#local D=div(D,104);M().5,2pigment{rgb M()}}
N(D)#end#end#macro M()<mod(D,13)-6mod(div(D,13)8)-3,10>#end blob{
N(11117333955)N(4254934330)N(3900569407)N(7382340)N(3358)N(970)}//  - Warp -
