Feeling creatively blocked? Try a pack of IDEO Method Cards, a tool that helps designers, innovators, entrepreneurs and others come up with new ideas, approaches and strategies for business and creative endeavors. Each card features a photograph, diagram, drawing or other image on the front and a suggested approach on the back. You don’t have to be a professional designer to appreciate how these cards can help you think about things differently or conduct thought experiments in the everyday world. IDEO provides four examples online; if you’re intrigued by these, you’ll hunger for the whole deck.
