CHILDHOOD AND EARLY LIFE
Born October 31 in Sta. Ana in Manila, Philippines. His mother, Magdalena de los Santos dies when Castrillo is a year and a half old. A fertile imagination begins to reflect in the toddler who remembers dreams, sees forms and figures on cracks and wood grains of empty walls. He takes pieces of marble, plays with reflections of the sun and visualizes forms inside the marble pieces.
Enrolls at the Ateneo in Padre Faura but drops out to finish gradeschool at the Sta. Ana Elementary School. He begins to draw figures on corners of notebooks, that, when skimmed in sequence, produce animation. He begins to fashion toys from tin cans. A fascination with the metal’s warped surface begins.
