Thonik specializes in visual communication with an emphasis on graphic design. Thonik likes to combine an integrated strategic approach with high quality design and an adventurous exploration of a broad array of media. Thonik's style is attractive and effective. Clear concepts are conveyed with a minimum of means. Thonik also has an anarchistic side and the graphic designers of Thonik regard each project as a chance to experiment.
