PHILADELPHIA (AP) -- All the pieces have fallen into place for the designer of a giant Tetris game.
Drexel University professor Frank Lee has earned the Guinness World Record for largest architectural video game display. Again.
Lee and two colleagues created a computer program to play the classic shape-fitting puzzle on two sides of a 29-story skyscraper in Philadelphia.
They used hundreds of lights embedded in the glass facades of the Cira (SEAR'-ah) Centre. All told, the "screens" totaled nearly 120,000 square feet (11,000 square meters).
Dozens of Tetris enthusiasts played the supersized version in April using a joystick from about a mile away.
The record announced Tuesday beat the previous one also set by Lee. Last year, he recreated the classic Atari game Pong on a single side of the same building.
