Just a quick recommendation for an amazing piece of work by Malaysian-born artist Hong Yi.
The portrait she’s posing with here, made over the course of 12 hours using coffee stains from a coffee cup, is of Taiwanese pop singer and songwriter, Jay Chou, whose song, Secret, opens with the lifting of a coffee cup off its saucer.
This is one of those works that is remarkable as much for the process used to make it as for the final product, and thankfully, via some photos from Hong Yi’s website, as well as a YouTube video, we are fortunately able to fully appreciate both aspects.

P.S. Be sure to check out another work by Hong Yi, a portrait of dissident Chinese artist Ai Weiwei, made entirely of sunflower seeds.

Excellent – thanks for posting this. I made sure to pass this link to my son who is studying computer art & 3d modeling. My wife is an art teacher and will share with her classes.
