His drawings are composed of simple shapes, smooth lines and experimental typography which make up intricate geometric and surrealistic worlds inhabited by mysterious characters, smiling animals and climbing plants, growing plants as a pattern in the spaces between the shapes of the letters. Jonathan describes his style as the digital evolution of his childish doodles. His simple light style i at the same time obsessively built, finding many favors, so that children of Anorak magazine for children (and parents aware that their children have the best of international creativity to tear up and to scribble) want it as their coloring book, as the Japanese want Uniqlo, Playstation as a guest interface design, and many others that you can find through its digital portfolio and his up-to-date Behance. His work accompanies small fanzines, posters, postcard, etc. self produced and delivered via web. In 2010, at last, Print recommended him as one of 20 designers and illustrators under 30 to watch.

Calugi has also produced t-shirts for Superfancy and Lovers Shop (me-you = sad overall) , as well as an Ipad and Iphone’s case in wood for Grove
