He himself could hear the harmony of the Universe, and understood the music of the spheres, and the stars which move in concert with them, and which we cannot hear because of the limitations of our weak nature (Porphyry, Life of Pythagoras) I love legends. The life of Pythagoras is ...

The Moonies are up on their mountain, the lunatics have taken over the asylum, waiting on the rapture (The Daily Mail, Radiohead) I have not write any post lately, maybe because I have been quite busy with other unexpected project or maybe because I am going through a deep creative ...

On candy stripe legs the Spiderman comes, softly through the shadow of the evening sun (Lullaby, The Cure) Cellular automata are an inmense source of artistical images. Today, I experimented with Cyclic automata, which are ruled with these simple rules: Create a grid of cells. Give a state to each ...

Spinning on that dizzy edge (Just Like Heaven, The Cure) This post talks about a generative system called Physarum model, which simulates the evolution of a colony of extremely simple organisms that, under certain environmental conditions, result into complex behaviors. Apart from the scientific interest of the topic, this model ...

Moça do corpo douradoDo Sol de IpanemaO seu balançadoÉ mais que um poema(Garota de Ipanema, João Gilberto) Sometimes I think about the reasons why I spend so many time doing experiments and writing my discoveries in a blog. Even although the main reason to start this ...

Ooh, see the fire is sweepin’Our very street todayBurns like a red coal carpetMad bull lost its way(Gimme Shelter, The Rolling Stones) After following this easy tutorial, you will be able to create tiled images from a photograph. You may want to use your own portrait or some ...

Sin patria ni banderas, ahora vivo a mi manera; y es que me siento extranjero fuera de tus agujeros (Tercer movimiento: Lo de dentro, Extremoduro) The technique I experimented with in this post is an endless source to obtain amazing images. It is called reaction-diffusion and simulates the evolution of ...

Mathematics, rightly viewed, possesses not only truth, but supreme beauty (Bertrand Russell) You have a pentagon defined by its five vertex. Now, follow these steps: Step 0: take a point inside the pentagon (it can be its center if you want to do it easy). Keep this point in a safe ...

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 . It’s always a source of inspiration for me. I recently discovered there the space colonization algorithm, concretely in this paper. Originally, the algorithm was ...

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 ...

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 ...

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 characteristics ...

La luna es un pozo chicolas flores no valen nadalo que valen son tus brazoscuando de noche me abrazan(Zorongo Gitano, Carmen Linares) When I publish a post showing my drawings, I use to place some outputs, give some highlights about the techniques involved as well as a link to ...

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 ...

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 techniques … ...

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 ...

¡Ay que ver cómo se estropean los cuerpos! (Pilar, my beloved grandmother) My grandmother was a master of sewing. When she was young, she worked as dressmaker, and her profession became a hobby with the passage of time. I remember her doing cross-stitch, embroidering tablecloths and doing crochet. I ...

Sin ese peso ya no hay gravedad Sin gravedad ya no hay anzuelo (Mira cómo vuelo, Miss Caffeina) I love messing around with R to generate mathematical patterns. I always get surprised doing it and gives me lot of satisfaction. I also learn lot of things doing it: not ...
