The code to generate this cartoon is in my answer to the XKCD-ification question. When executed in Mathematica, there is even a secret mouse-over message.

comment FindMaximum slow for fixed parameters
Maybe you could find a simpler problem (with code that can be run) that shows the same behavior? It's almost impossible to figure out what's happening when we have no idea what the functions are.

comment How to find out where an error occurs?
Break your code into cells and evaluate a few lines at a time. When they all work, consolidate them.

comment Polar color coding for complex function plots?
Who drew this picture and what software did they use? It appears to be a "standard" Riemann zeta function plot (findable on lots of websites), but to really answer your question you would need to know how much of this is data-driven and how much is gloss and photoshop.

comment How to calculate the phase spectrum
Have you looked at the command FourierTransform? Or maybe (because you have the symbol s), you want the LaplaceTransform? Plot is useful for showing your results.

very clever -- I hadn't realized that Locators are just another graphics object.
