Belgian artist Ben Heine, better known for his clever series Pencil Vs Camera, has created a new and pretty unique technique he calls Digital Circlism, where he creates portraits of celebrities from thousands of colored circles.
 

“I usually apply each digital circle individually on a black background with a sharp round brush in Photoshop CS4. I usually make bigger circles in the lighter areas of the subject and smaller circles in the darker places. This gives more volume and a 3D illusion. There is no limit, it’s a new technique and I think there is much more to do with it.”
