Using a portrait of Russian Mathematician Grigori Perelman by artist Jules Julian, designers Alan Temiraev and Volodenka Zotov created a beautifully designed pencil set. The packaging is designed so that when intact, the eight individually boxed graphite pencils make up the illustrated portrait, by Jules Julien, of the Russian mathematician Grigori Perelman, famous for solving the the legendary Poincaré Conjecture. via
