// copy machine by Olaf Doschke

// This code resembles a simple
// copy machine, which creates the
// original and a series of copies,
// each made of the previous one.
//
// In this case it rotates the copy
// by 6 degrees and it's a 


// PRECAUTIONS:

// Needs option +KFF<N> to work,
// with N as you like, but reasonably
// 10 to 99 with this long version.

// the short version c.pov only works
// with +KFF9

// concat() needs to be modified
// according to the length of the
// final frame number and the name
// of the script.        


// the scanning light of the copy machine:
light_source{0 2.6}

   // scene of this or previous
