Giant Tetris game on skyscraper marks 30 years

A giant game of Tetris has been played on the side of a Philadelphia skyscraper to mark 30 years since the game was developed.

Hundreds of LED lights were attached to the Cira Centre building by organiser and game designer Frank Lee, who previously holds the Guinness World Record for the largest architectural game display for a similar event, Pong in 2013.

Game designer Lee said the skyscraper Tetris project "was a personal love letter to the games I loved as a child."
