The Art of Looking Sideways is an awesome book by Alan Fletcher. I just bought a copy.
I had blogged about it earlier also on SaurabhGarg.com (on 13th Jan 2008).
This book should help me with a lot of inspiration about design, advertising, creativity, decision making and thinking. Looking forward to reading it.
And now this book becomes the second most expensive book that I have purchased after Still Reading SRK.
