An anonymous reader writes: Today, as every May 25th, geeks all over the world celebrate Towel Day and carry a towel in honor of Douglas Adams. The popular author of The Hitchhiker's Guide to the Galaxy died in 2001 at the age of 49, but his work lives on. According to the book, a towel is about the most massively useful thing an interstellar hitchhiker can have. Hence its symbolic role in this celebration. This year, for the first time as far as we know, Towel Day is being supported by the British publisher of Adams' books, who organizes a photo competition.
