CocoCurveGen

The great advantage of CocoCurveGen is that you can see the curves in your curve editor and modify their properties (e.g. wavelength, offset) using sliders instead of having to type values into an expression. You can use the resulting curve for all kinds of things. Connect CocoCurveGens output value for example to a grade node for a flickering light effect or transform node to create a camera shake.

Thanks goes to David Emeny for providing the wave expressions I used.
