Regular Christmas trees have a string of lights. High-tech trees have 30,000 LEDs, 43 LCD televisions and lasers. Get the picture? Good—because the following trees definitely fall into the latter category.

Sharp's Aquos LCD Tree: This year Sharp unveiled a 26-foot tall Christmas tree in New York's Grand Central Station constructed out of 43 televisions ranging from 19 to 52 inches. As part of the promotion, Sharp is giving away televisions from the tree to those who register. They will also donate $1 per entry to the Green Collar Project—a program that trains people to work in environmental jobs. [Sharp via Link Image via NYClovesNYC]
