Hi! The mural is a powerful piece of art for sure. Not just a commemoration - it keeps the sense of sacred space that was created with the spontaneous altar of offerings from the community in the days after the attack. Here's a photo of part of it via Wikipedia, but it stretched for half a block.

Sadly, in looking for photos of the original memorial, I found an article that sounds like they destroyed the mural, suddenly dubbed "temporary," a year ago. Augh.
