On Saturday, more than 11,200 Lebanese had gathered in Martyrs' Square to form a human Lebanese flag.
Squares of colored cardboard - green, white and red - were distributed to the participants, who were assembled into position to form the nation's symbol.
"This event is our civilized way of expressing our solidarity and attachment to our country," said Tony Moukhaiber, the "voice behind the microphone" cheering on the crowd with zesty slogans while patriotic songs played in the background.
The flag took place in front of the Al-Amin mosque in central Beirut, facing Hariri's grave.
Thousands of men and women from all across the country began to gather at the square at noon to be part of the event.
Oumayma Loutfi said: "I departed from Baalbek this morning. I'm here with my three children, husband and mother-in-law."
Many opposition MPs also participated in the event.
"You are Lebanon's pride," shouted Zghorta MP Nayla Mouawad, while Beirut MP Ghinwa Jalloul congratulated the crowd for their patriotism and organization.
Jalloul said: "This flag shows how Lebanese people are faithful to Rafik Hariri's memory and how they won't rest until they find out the truth about who killed him."
At 3 p.m. sharp, the participants raised their squares high in the air forming a giant Lebanese flag for the cameras filming the formation from atop the Al-Amin Mosque, with the national anthem blaring out all the while. "This is the biggest flag in the smallest country," Moukhaiber screamed into his microphone.
