It should be

    var t = texture().lines().stroke('red')
    if(this.button.on) t.heavier()

Wow! Thanks.

Interesting point of view. Choices of style apart, there are situations where textures are useful. Like for example the case faced by swayvil (see the comment), or when you need b/w printable images. Another good reference is "Semiology of Graphics" of Jacques Bertin, he has a good opinion about textures.

:D thanks! Very good point.

Many thanks for the good words! I am happy you like it.

Textures and colors can be combined, for example if you need to select according two different group of categories/variables.

Pykov implements the computation of some of the most common quantities related to discrete-time finite regular Markov Chains, namely: steady state, mean first passage times and absorbing times. The calculation are performed by means of the analytic formulas described on Kemeny&Snell, and the steady state is derived with the inverse iteration method. If you are interested on random walkers, pykov offers a handy way to generate them and evaluate their probability. Sorry, I do not know PyMC well enough to say if the above quantities can be calculated also with it.

I coded this library during my PhD, where I applied Markov Chains to the study of protein folding dynamics. I am quite confident with it, but as far as I know few others used it. At that time, I used pykov with networks of around 100k nodes and 500k links. Only recently I replaced pysparse with scipy sparse solvers. Entire methods are comment out because they are heuristics that do not belong to the standard Markov Theory, and they can be removed.
