Mar de versos –Sea of Verses- is a poetic digital work that explores the automatic generation of verses with the creation of the right atmosphere to its reading that includes images and sea sounds. It is programmed in HTML5, javascript and CSS3 using many of the options of this language. It is necessary to turn on the speakers to listen to the sound of the sea. Mar de versos use a technique of patterns –templates-to generate the verses with a wide basis of data from phrases and other words or sub-phrases that can fit with the patterns, therefore poems of different quality are created randomly.
