What is the ODE you're trying to plot the trajectories of?

comment interpolating a smooth closed surface to a non-uniform data set (ListSurfacePlot3D)
Perhaps you could convert the data into spherical coordinates, perform interpolation of $r$ as a function of $(\theta, \phi)$, and use SphericalPlot3D. (Or analogously: cylindrical coordinates, $r$ from $(z,\theta)$, RevolutionPlot3D.)

comment How can I visualize a map $f:T^2\to T^2$?
What is $zw$ when $z,w\in S^1$? Are we interpreting $S^1$ as a subset of $\mathbb C$?

comment How to merge several partially overlapping screenshots into one image?
You don't need to crop it exactly, you just need to get rid of the top bar assuming you know roughly how big it is.

comment Ugly rendering of curve with ParametricPlot3D and NDSolve
Just doing Plot[Sin[k x], {x, 0, 1}]] with a very large k should be an MWE, shouldn't it?

comment Ugly rendering of curve with ParametricPlot3D and NDSolve
If you turn down MaxRecursion to like 0 or 1 then it should be safe to increase PlotPoints beyond 1000.

comment How to merge several partially overlapping screenshots into one image?
Life would be easier if you first crop out the top of image2, image3 etc before attempting anything automatic.

comment Can Mathematica solve Plateau's problem (finding a minimal surface with specified boundary)?
@Michael: Well, you can try defining a different initial surface that is closer to the solution. My createInitialSurface is a pretty simple starting guess, not a silver bullet. As for drawing Gauss maps, I don't know anything about that, you could ask a new question.

The last image itself seems like a good picture of the noise.

comment How to plot list of numbers in the complex plane?
@Lovsovs: Note carefully the presence of parentheses around (x /. sol) in my comment and in the first half of murray's answer.

comment How to plot list of numbers in the complex plane?
sol is not a list of complex numbers. sol is a list of replacement rules, each of which replaces x with a complex number. So you should plot (x /. sol) instead of sol directly.

comment Do Any of the filter functions perform a LOESS or LOWESS filter?
I don't think you understood my comment. What does that have to do with the difference between loess and lowess? Wikipedia and Mathworks say the difference is between linear and quadratic regression, R and the stats SE answer say the difference is between bivariate and multivariate data, but everyone agrees that both do a local weighting that falls off near the edge of the window, unlike your comment. Anyway, if you're looking for a locally weighted regression, my answer linked by MarcoB does do that.
