I was born within walking distance of Ogikubo Station in Tokyo, and by the age of ten or eleven, I was using the subway system to get around the city to take foreign tourists to see the sights, earning myself a bit of extra LEGO money. Australian LEGO Certified Professional Ryan McNaught and his team of builders spent more than two hundred hours building this complete Tokyo subway system map from 31,000 LEGO bricks, showing all thirteen lines in their distinctive colors (my favorite line is the Chuo line in orange). The mosaic measures 4.6 meters (over 15 feet) wide and 2.6 meters (8.5 feet) tall, dwarfing the rather tall bloke standing nearby.
