Technical data for this type of fractal : click here (C07-010).

For the fractal here :
fn1() = ident(), fn2() = sin(), fn3() = sin(), fn4() = recip().

real(p1) = 1, imag(p1) = 19, real(p2) = 2, imag(p2) = 2, real(p3) = 1, imag(p3) = 1
This fractal represents a very curious image. It is another area of the previous fractal (C07-030).

If real(p2) = 2 instead of 1, the shape of the fractal is very different :
