This fucking guy.

We’d mentioned how blown away by the design and technology behind the web site for DJ, producer, and musician j.viewz back in January, when we included a track of his on our mixtape for that month. Now, he’s teamed up again with site designers and digital creative agency Hello Monday to once again blow our minds.

The mobile, app-based video for his new song, “Almost Forgot” is tempo-driven and affected by your heartbeat. As you watch and listen, by placing your finger over your mobile device’s camera, the rhythm and video itself pair themselves with your heart rate, reading it by perceiving subtle changes in your finger’s skin color along with each beat of the heart.

Totally beautiful and innovative.
