comment Finding a number which has the same remainder when dividing certain other numbers
@shrx Taste? I personally find n=n+1 to be a bit more clear. I am aware that a good C compiler will replace n=n+1 with n++ but I think there's not much difference in Mathematica. If anything, n=n+1 is very slightly faster.

Very nice! I don't know that LaplacianFilter existed when I first did this. :)

comment Iteration of multiple functions that feed into each other
I recommend you write a single function T[{S_, c_, y_, x_, t_, F_}]] and iterate a few times starting from a list of length 6 using NestList first. As others have observed, there are some questionable points in your function definitions, so I'm hesitant to jump in myself.

comment Nonrectangular region for NDSolve
I responded yesterday with a similar answer but deleted it when I realized that my approach did not deal correctly with the Neumann type boundary condition at the top. The problem is that your transformation does not preserve orthogonality on the top boundary thus, a Neumann condition in the (x,y) plane doesn't translate to a normal derivative in the (u,v) plane. Furthermore, NDSolve doesn't work when non-normal derivatives are are included as boundary conditions, it issues an NDSolve::bcnorm error. I could temporarily un-delete my answer, if you like.

comment Extract Style Attributes from Style[]
@rm-rf So you'd like Equal[var2,var1] to evaluate to True in the same way that Equal[1,1.0] evaluates. I can see that. But, are there other situations where Equal[a,b] evaluates to True where a and b are non-identical, non-numeric expressions? I'm not sure off the top of my head, but I haven't been thinking about code so much lately. It's a little far afield of the OP's intention, perhaps. :)

comment Extract Style Attributes from Style[]
@rm-rf Isn't there? var2 = Style["aString", Bold, 24]; var1 = Style["aString", FontWeight -> Bold, FontSize -> 24]; OrderedQ[{var2, var1}] returns a reasonable result. Do you want var1 and var2 to be the same?

comment Is it Possible to change dashes into circles with Plot command?
Very nice! One big advantage is that your approach is independent of the AspectRatio of the figure, while mine only works in true aspect ratio, though that shouldn't be hard to adjust. It might be work mentioning that your interpolated function arc has the form arc[s]={x,y}, where s is distance traveled along the arc and {x,y} is the resulting point, i.e. it is exactly the arc length parametrization.

comment Is it Possible to change dashes into circles with Plot command?
Thanks! I was aware of the EllipticE thing, but figured the resulting function would need to be inverted numerically anyway. As I think of it further, perhaps the special function representation arcLength could be passed to InverseFunction or some such? Seems overly mysteriious, though.
