@Kuba: The implementation I have is written in Java, and is open-sourced here: sourceforge.net/projects/flamethyst Some images created can be found here: people.su.se/~peal0658/index.php?page=fractals

Google "Flame fractals". I create this type of fractals a lot; 10⁵ is not nearly enough iterations. You would like about 2000 iterations PER PIXEL in the final image to get a decent result.

Ah, yes, of course! I feel silly now.

comment State “i” goes to state “j”
I would guess it means states accessible from either 1 or 4.

Thanks! Absolutely not, I was just a bit lazy to add it myself :)

comment Finding lags of time series with `Do`
Oh, L[t_]:=t-k; should most definitely work. But dont use capital letters as variable names, these might already be used by Mathematica, in any case, it is bad practice.

Oh, you want ListPlot[L/@Range[5,100]]

@belisarius cf = Flatten[stuff,1] can be optimized to cf = Join@@(stuff).

comment Generating Gelfand-Tsetlin patterns
@IstvánZachar Are there any performance issues with Return? I read that it is a bit quirky, and is more "procedural" than "functional", so is it something to avoid in general?

comment Generating Gelfand-Tsetlin patterns
@IstvánZachar Oh, ok, is there a particular reason why one wish to avoid return? I am probalby just used to Java, so it feels easier to read in this manner.
