Blooming Epiphyllum oxypetalum (queen of the night) time lapse

Epiphyllum oxypetalum also known as queen of the night is an epiphytic cactus native of Central America. Its large strongly fragrant flower blooms for a single night only. This is from my first attempt in time lapse photography in 2007. This time lapse is consisting of about 700 out of 1,500 photos taken; the rest are unusable because the flower rotated during blooming and moved out of the frame!
