    only one. For instance the X pendulum has only influence on the x
    coordinate of a dot, it is computed: "x = radius * cos (time)". The
    first selector allows you to swap out the cosine function. Instead you
    could get sine, tangent, cotangent, secant, cosekcant and the hyperbolic
    twin of the already mentioned functions.

    The second selector has five options: "= + - * /". If you choose the
    first (equal sign) your time variable will be just swapped out with
    another variable. The other four option describe the operation that will
    be applied upon you time value. So e.g. if you select plus the resulting
    formula will be "x = radius * cos (time + (...))". The allude to
    whatever you will choose with the next three selectors.

    Selector three and four are just factors. They contain natural numbers
    and natural constants you can multiply the variable with. And last not
    least selector five holds the variables time frequency and
    radus/amplitude of each pendulum. This allows you for instance add the
    (always) current pendulum frequency of pendulum W to the time value of
    Pendulum X resulting in unpredictable shapes. There is lot to explore.

    Pendulum W affects the x and y coordinate, hence it has two rows for
