The world’s largest touch screen is 10 meters long and can accept up to 100 multi-touch inputs at one time. (See the video!)

The screen was developed by a group at the University of Groningen in the Netherlands. In order to create the behemoth, the school modified a 3D theatre’s screen using infrared lamps and cameras. The screen is used to teach students interactivity.

The world’s smallest book must be read using an electron microscope.

This first-ever nanoscale book was published as a work of art in April 2007. This book, called Teeny Ted from Turnip Town, measures 0.07 mm by 0.10 mm!! Each letter was carved on a polished piece of single crystalline silicon by a focused-gallium-ion beam. The beam had a minimum diameter of about 7 nanometers, or only 70 ATOMS!! The story is written on 30 microtablets, each measuring at about 11 by 15 microns.

Facebook’s oldest user is 103...and she updates from an iPad.

Lillian Lowe, 103, posts her Facebook messages from her grandson's iPad

Great-grandmother Lillian Lowe has taken the title of oldest Facebooker from 104-year-old Ivy Bean, who died in her sleep this past July. Lillian checks her wall about twice a week and is friends with 34 different people, including 7 grandchildren and 13 great-grandchildren!

Born in 1907, Lillian has seen all kinds of changes during her lifetime - the sinking of the Titanic, two World Wars, the first computer, and now the advent of social networking and tablet computers!

Thanks to the publicity that comes with being dubbed the oldest person on Facebook, she has recently received over 900 Facebook friend requests. She says she has also heard of Twitter, but does not know what it is.
