This project is from 2010, but it's such an amazing and unusual achievement it's still worth sharing today. Artist Pete Fecteau created a huge mural commemorating Dr. Martin Luther King, Jr. out of more than 4,000 individual Rubik's cubes, with each square on each cube hand-arranged to create the detailed image you see above.
On his blog, Fecteau says the mural measures nearly 10 feet tall and almost 20 feet wide. Assembling the 4,242 cubes in the necessary arrangement took 40 hours. Entered in the 2010 ArtPrize competition in Grand Rapids, Michigan, the mosiac, titled "Dream Big," placed in the top 50 from over 1,700 submissions. Read more about it here at MyModernMet.
Pete's still doing art and design work today—check out his work here, including his plans for an 8,484 cube mural dedicated to Albert Einstein. He's using Rubik's cubes in a more productive and artful way than just about anyone I know. [MyModernMet; Pete Fecteau via @BurritoJustice]
