let's just make up stuff

make yourself a Kipp's apparatus filled with iron(II) sulfide and hydrochloric acid.
It works and looks awesome.

flames, or "fire", as you may call it, are just the gases burning.

I'm trying to make it work in mathematica
little success so far: I found a code which I don't yet fully understand

code:
Maurer[f_, \[Phi]_, d_, m_] :=
With[{F = Function[\[Phi], f]},
Table[Line[
Table[{Re[F[(2 p \[Pi])/m]], Im[F[(2 p \[Pi])/m]]}, {p, p0,
LCM[m, d] + d, d}]], {p0, 0, GCD[m, d] - 1}]]

f[x_] := 20 x
Graphics[{Maurer[Sum[(f[j]) E^(j I \[Phi]), {j, 0, 2}], \[Phi], 100,
200], Circle[{0, 0}, 3 f[1]]}, PlotRange -> All, Axes -> True]

how do I set a custom line spacing in the header of a LaTeX document? I want to increase the gap between the text in the header and the horizontal rule at the bottom of the header.
