Emil Nava is as slick as he is prolific, and he certainly proves that with this video for Calvin Harris and Rihanna's This Is What You Came For - his eighth video this year.Occupying a huge, white, otherworldly cube, Rihanna takes centre stage as her surroundings chop and change around her. Using a combination of exterior shots, projection mapping and lasers, Nava and his team produce some incredible visual illusions, including an awesome piece with a parked car and some cool perspective trickery.
