To celebrate the 50th anniversary of LEGO blocks being introduced in Japan, the Danish company organized a cross-country workshop called âBuild Up Japanâ in which over 5,000 children created their visions of future Japanese buildings. The assembled pieces were all brought to Tokyo and assembled as a giant white map. Rather than recreating existing landmarks, the adorable children were encouraged to use their imaginations to create what they wanted Japan to look like. The results look pretty remarkable. In total, 1.8 millions LEGO blocks were used and a stunning metropolis was born. [source]
