Cereus Night Blooming Cactus

My smaller Cereus cactus bloomed the other night. I was hoping to put a webcam attached to a Raspberry Pi computer to time lapse photograph it opening and closing during the night. The night the bloom opened I only got the camera set up late in the morning so the bloom pod had already mostly closed.

I did capture a small about of video of it for several hours which I need to figure out how to edit and put on YouTube.

Interesting enough it looks like amazon.com sells seeds for a blue variety of this cactus.
