Making skydiving more realistic

Question

Consider the following MWE:

\documentclass[export,border=5pt,tikz]{standalone}
\usetikzlibrary{decorations.text,calc}
\begin{document}
\foreach \n in {0,1,...,10}
{
    \begin{tikzpicture}

%       \pgfmathsetmacro{\w}{(-1)^\n * (\q/20)}
        \pgfmathsetmacro{\w}{4*cos(\n r)*\n}
        \begin{scope}[xshift=-.5cm,yshift=-\n cm,rotate=\w]
            \draw (0,0) circle(.5);
            \draw (0,-.5) --+ (0,-1.5) --+ (.5,-2);
            \draw (0,-2) --+ (-.5,-.5);
                \draw (-1,0) -- (0,-1) --+ (1,1);
            \fill[black,radius=.05] (-1,0) circle;

        \end{scope}

    \begin{scope}[xshift=-.5*\n cm]
        \fill[yshift=6cm,rotate around={(45:(1,0))},rounded corners=.5cm] (0,0) rectangle (2,-4);

        }
        \draw[xshift=-3.5cm,yshift=5.05cm,line width=3pt] (0,0) --+ ([yshift=.1*\n cm]2,-.5);
        \draw[xshift=2.5cm,yshift=5.05cm,line width=3pt] (0,0) --+ ([yshift=.1*\n cm]-2,-.5);

        \node at (7.3,6) (a) {\large \TeX.SX rocks!!!};
            \draw[thick] ([xshift=-.1cm]a.north west) -- ($(a.north west)!.2!(a.south west)$) -- ($(a.south west)!.2!(a.north west)$) -- ([xshift=-.1cm]a.south west) -- ([xshift=.1cm]a.south east) -- ($(a.south east)!.2!(a.north east)$) -- (a.north east) -- ([xshift=.1cm]a.north east) -- cycle;
                \draw ([yshift=-.2cm]a.north west) --+ (-2,0);
                \draw ([yshift=.2cm]a.south west) --+ (-2,0);
    \end{scope}
    \end{tikzpicture}
}
\end{document}

My questions are:

• How can the "node-drawing" move sinus-like in the wind?
• How can the stick figure move down in a "zig-zag-rounded way" (imagine the stick man moves in a zigzag like way down, but the edges between two consecutive points of the zigzag-line is rounded)?
