Along with his work in watercolour on paper, Grillet works with another support, viz., small tablets of blue pigment, like those found in paint boxes. Applying small dabs of white paint to them, he patiently creates starry Lilliputian landscapes, miniature firmaments and silent night skies in a shift of scale that condenses the immensity of nature into a few nuances of colour, for a timeless work of art.
