Base Two is always looking for great ideas and we find great inspiration from design around the world. We particularly liked this Annual Report that was created for Austria Solar by the agency Serviceplan Campaign. Its particularly fitting as Solar energy is the main business of the client Austria Solar. This is the first annual report powered by the sun. Its content remains invisible until sunlight falls on its pages. How cool is that. We can honestly say it caused quite a stir when we first saw it round the office.
