christmas lights

it's a little hard to see here, but they put gels on the lights at the top of the towers---red on the north and green on the south---unfortunately the lighting is not bright to begin with so the green sorta disappears---and there are actually a lot of xmas trees in the buildings, including two or three blue ones and the upsidedown one that i posted before although my euphorbian xmas tree is one of the few visible in this image
