Valentines Day is tomorrow, and Soho-based post & VFX house Rushes has released this promo video featuring copulating animated animals across a notebook page.

Accompanied by Marvin Gaye's Lets Get It On, the camera drifts across an open notebook covered with drawings of hearts and humping animals, which spring to lift and start merrily screwing away. A chain of hearts dances around the animals.

The naturalistic VFX are spot on, and the ad showcases some well-designed tracking, animation and compositing.
