String art generator

This project began with the idea to build a square grid of n x n nails. Then a thread could be weaved between the nails. The thread is a continuous one, without breaks, and you can change the color in a palette of 5 by clicking or touching the screen.

The initial idea was to weave yourself interactively, then I thought an algorithm could be responsible of that. In the final version you can weave yourself in addition to the generated pattern anyways.

Binary landscapes

It’s mind-bending how just a very simple mathematical operation such as applying a binary operator to the coordinates on a bitmap can generate such a huge collection of unique and extraordinary images.

In “binary landscapes” with just a few lines of code we use three different binary operators to the coordinates (or,xor,and) for instance (x or y) and then divide it to another number and getting the remainder. The result is used to paint a color for this exact pixel.

The result is a huge collection of pseudo-fractal images which evoke impossible landscapes, crowded cities, glitchy psychedelic with vivid colors or just beautiful patterns. All of them are deterministic given its initial parameters. There is no random intervention.

ReacT 2020

I remember when I was a child and one day they took us on a school trip to the old science museum in Barcelona. There one of the things that caught most my attention was a sand pendulum that you could throw and that made some very beautiful and harmonious shapes on a board.
20 years later, at the end of the last century, I was still fascinated by these parametric curves and by the generative art of computers in general. For instance for the work of the Austrian artist Lia. It was 1999 and I thought of presenting myself at the Prix Ars Electrònica, in a few days I made my own work called ReacT, it was an interactive digital animation in different phases where the common element were black and white rectangles that moved generating various forms and challenges that the user had to solve. Sergi Jordà suggested me that I could use some sounds created with his Fmol tool (where i was contributing aswell) as a musical background.

I was awarded with an honorable mention in the net-art category.

This first version is not available, since it was done with the old Director / Shockwave platform. Then I implemented another version coded in Java

20 years later I go back to the fascination of parametric curves, simple and in black and white, but this time in 3D using threejs. I hope you like it. Put on some good music, play with the shapes, and enjoy as if you were mesmerizingly contemplating the flames of the fire on a cold winter night.

Bon 2020 – Calidoscopi interactiu

Per felicitar el 2020 hem creat un caleidoscopi interactiu, tant en la part visual com en la sonora, que reacciona tant amb el moviment del cursor com amb el clic.

El codi està bifurcat de @Eugene i el so generat amb Tone js

Flux MX

Flux MX is an interactive visualization that shows the flows of credit card transactions between different cells and zip codes while combining information from Foursquare.

The display allows you to filter by categories in each of the cells and shows the input and output flows between the different cells and zip codes.

The application displays the activity in cells with different types of commercial, residential activities, etc.

Flux MX won second prize in the business category of the Innova Challenge MX competition organized by BBVA.

The competition, which has had the participation of 378 developers from 36 countries, sought innovative solutions using the BBVA API created for the occasion that allows you to get data on BBVA card transactions in 3 cities in Mexico in a period of 6 months.
