Roberto Campus
Illustrator · Composer · Coder · Theorist · Author
Born in Sardinia in 1974, Roberto Campus grew up near Rome asking the kinds of questions most people learn to set aside. Thirty-five years later, he is still asking them. In the meantime he built a body of work that moves without apology between fantasy illustration, orchestral composition, software engineering, theoretical physics, and fiction — not because he could not choose, but because they are all forms of the same search.
