English: In its booth on the International Consumer Electronics Show floor, Intel is displaying an 18-foot-tall "tree" with 176 Ultrabook systems hanging from the "branches." The interactive installation features systems from manufacturers including Acer, Asus, Dell, HP, Lenovo, Sony and Toshiba.

The "Touch Tree," as it's called, has seen a steady stream of people since the CES exhibit floor opened on Tuesday morning at the Las Vegas Convention Center.

A touchscreen app on the five Ultrabook convertible devices at the base of the tree lets people swipe shapes, which Intel calls "blooms," that then travel up the trunk and move across the screens of the devices that form the tree "canopy."
