Phantom towers, ghost-lights really
Annette Marie Hyder

Ignis fatuus, Will-o'-the-wisp
flickering lamp of recall
two long fingers of light
point toward the sky
accusatory testament
to Twin Tower's bright fall.


Wikipedia lists the Tribute in Light as an art installation of 88 searchlights placed next to the site of the World Trade Center to create two vertical columns of light in remembrance of the September 11 attacks.

The Tribute in Light is an art installation of 88 searchlights placed next to the site of the World Trade Center to create two vertical columns of light in remembrance of the September 11 attacks. It initially ran as a temporary installation from March 11 to April 14, 2002, and was launched again in 2003 to mark the second anniversary of the attack. As of 2010, it has been repeated every year on September 11. It had been announced that 2008 would be its final year, but the tribute was continued in 2009. On December 17, 2009, it was confirmed that the tribute would continue through to the tenth anniversary of the attacks in 2011.
