The World's Largest Design Competition
"In April 2003, the Lower Manhattan Development Corporation launched what became the largest design competition in history. Across six continents, from 63 nations and 49 states, 5,201 individuals answered the call to honor all who were killed in terrorist attacks on September 11, 2001 and February 26, 1993." This web archive provides access to all 5201 submissions and is searchable by country, US state, and name of competitor or team member.
