His first German project was "Mextoys", 2003–04, 80:00", commissioned by the Festival Eigenarten and the Culture Ministry in Hamburg and premiered at the city's prestigious Hochschule für Musik und Theater in Hamburg. This piece constituted a breakthrough in Sandoval's work: it was his first true "phenomenological" work, his first full multimedia piece and his first work joining video and music into a single conceptual and constructive layer. This point marked Sandoval's departure from traditional score writing and deterministic thinking, towards developing either an experience-oriented connection to music and a Piagetian approach to animism towards music and life in general. Jean Piaget's theories of language as an object and the cognitive inability to distinguish the external world from one's own psyche, still have a strong influence in Sandoval's work in this and the coming creative periods. Sandoval identifies himself also with diverse Edmund Husserl's phenomenological concepts like Lifeworld ("In whatever way we may be conscious of the world as universal horizon, as coherent universe of existing objects, we, each "I-the-man" and all of us together, belong to the world as living with one another in the world; and the world is our world, valid for our consciousness as existing precisely through this 'living together.'), "Empathy and Subjectivity" (the subjectivity of others, as well as our intersubjective engagement with them), Evidence ("the successful presentation of something whose truth becomes manifest in the evidencing itself"), Intuition ("...having a cup of coffee in front of you, for instance, seeing it, feeling it, or even imagining it: these are all "filled intentions", and the object is then intuited") and Intentionality of consciousness ("the power of minds to be about, to represent, or to stand for, things, properties and states of affairs"). All these concepts are linked in Sandoval's work with an ethical use of technology, (or Technoethics: using technology not just without renouncing to humanism but stressing and empowering Humanism).
