In 1998, American artist JK Keller began a massive photo project. Every day for eight years he photographed himself. This very cool video is the result.

Each self portrait lines up perfectly with the next, allowing us to seamlessly see the aging process.

But this project is about more than wrinkles and extra weight. I loved watching the little things, like JK’s transition from glasses to contacts and the evolution of his hairstyles.

But it must be said: this video is best viewed with the sound down. The relentless techno soundtrack is ear-piercing and definitely detracts from a brilliant piece of work.
