Google has brought the world of Tom Sawyer and Huckleberry Finn to its Home. The Search giant has its first ever panoramic doodle today, a googlingly happy birthday to author Mark Twain.

What you will find interesting is that the logo is a triptych, as well as being a panorama. A triptych is a work of art divided into three sections. Triptychs were rather hot in ancient Rome, and the form has shown persistence in modern times, especially in jewelry and knick knacks.
