Rainbow CN Tower

I was taking photos of the CN Tower when the Tower suddenly switched to a lighting scheme that I'd never seen before. I assembled this HDR image from exposures of 1/8th, 1/15th, and 1/30th of a second, all at ISO 6400 and f/5.6, taken with a Canon Rebel T2i digital SLR and a Canon IS 17-85 mm zoom lens zoomed to 61 mm. The HDR image was aligned using Photoshop CS5.1, and toned with Picturenaut.
