Flowers for Julia
Tweet No hables de futuro, es una ilusión cuando el Rock & Roll conquistó mi corazón (El Rompeolas, Loquillo y los Trogloditas) In this post I create flowers inspired in the Julia Sets, a family of fractal sets obtained from complex numbers, after being iterated by a holomorphic function. Despite of the ugly previous definition, the mechanism ...

Tweet Condenado a estar toda la vida, preparando alguna despedida (Desarraigo, Extremoduro) I live just a few minutes from the Spanish National Museum of Science and Technology (MUNCYT), where I use to go from time to time with my family.

Rcpp, Camarón de la Isla and the Beauty of Maths
Tweet Desde que te estoy queriendo yo no sé lo que me pasa cualquier vereda que tomo siempre me lleva a tu casa(Y mira que mira y mira, Camarón de la Isla) The verses that head this post are taken from a song of Camarón de la Isla and illustrate very well what is a strange attractor in the real life.

Tweet One cannot escape the feeling that these mathematical formulas have an independent existence and an intelligence of their own, that they are wiser than we are, wiser even than their discoverers (Heinrich Hertz) I love spending my time doing mathematics: transforming formulas into drawings, experimenting with paradoxes, learning new techni...

Allusions to parents in autobiographies (or reading 118 books in a few seconds)
Tweet If I keep holding out, will the light shine through? (Come Back, Pearl Jam) Imagine that you are writing the story of your life. Almost sure you will make allusions to your parents, but will both of them have the same prominence in your biography or will you spend more words in one of them? In that case, which one will have more relevance...

Kites and Darts: the Penrose Tiling
Tweet Agarrada a mis costillas le cuelgan las piernas (Godzilla, Leiva) Penrose tilings are amazing. Apart of the inner beauty of tesselations, they have two interesting properties: they are non-periodic (they lack any translational symmetry) and self-similar (any finite region appears an infinite number of times in the tiling). Both characteri...

Tweet For a lonely soul, you’re having such a nice time (Nothing in my way, Keane) In my previous post, I created the P2 Penrose tessellation according to the instructions of this post. Now it’s time to create the P3 tessellation following the same technique I described already. This is the image of the P3 tessellation: Note that all tiles...

Clustering Frankenstein
Tweet Necesito para estar sentado, un arbolito en este descampado (Desarraigo, Extremoduro) From time to time I come back to experiment with this stunning photograph of Boris Karloff as Frankenstein’s monster. I have done several of them previously: from decomposing it into Voronoi regions, to draw it as a single line portrait using an algori...

Colonizing Franky
Tweet Y otra vez me arranco despacito, al sentir que nada necesito (Locura transitoria, Extremoduro) One of my favorite sites in the Internet is algorithmic botany .
