Im using pintrest all the time. Especialy in my work office when i need to do a lot of different projects. And the worst thing about it is that you cant get out when you in it. It's impossible. Every single picture have related pins that keeps you busy. But the main way to find inspiration is actualy to go outside and look at the environment around you. At every single sign, billboard, leaflet, flyer, poster - even urban architecture - bridges, roads, maps or simply pack of cigarettes or chips - everything is inspiring if you can look at it at a right angle.
