This project is an interactive application written in collaboration with Vittorio Milone and requested from the artist Diego Cibelli, that has wrote and provided the multimedia materials. The application consists in a video and hypertext available through dynamic buttons. The circular buttons are considered as “particles” that can collide. Have been used algorithms for the simulation of a particles system in processing language (https://processing.org/) while the code of the web application has been optimized in processing js (http://processingjs.org/). The use of the hypertext is given by clicking on the numbers assigned to each particle different for color and group or text and topics.
