This link takes you to an interesting case study posted by RGD about making info graphics for an IT publication. It shows the rough ideas and the finished products, highlights the budget and audience and rationales. Really handy stuff over there at RGD!
Here you will find a fantastic presentation by partner at Pentagram Designs Harry Pearce about how he finds inspiration all around him, and how ideas have found him. He talks in this video about how looking in strange areas have inspired great ideas, how he can find meaning and beauty that was not intended by looking at things in a different way. He illustrates this by showing examples of “beautiful typography” he has found in places like India, Cuba, and the middle east that were not intended as beautiful typography, but caught his eye.
His message is to look at everything you see with aesthetic interest. Try to find beauty in everything. Stop and smell the roses.
