Consultant Greg Krehel is really, really into cactus. Krehel cares for more than 100 different types of echinopsis cacti, a group of species native to South America with flowers that bloom within a few hours. When the vibrant cacti start to bloom, Krehel grabs his camera, shooting high-definition timelapses of the flowers blooming (and sometimes wilting) over the course of one night in a makeshift photography studio he set up in his bathroom.
His videos will give you a new appreciation for cacti:
