Here’s a time-lapse video of Bricks 2 Pics making an image of a Route 66 shield entirely from Lego pieces. Most impressive.
According to the video, more than 4,000 pieces were used to make the shield. The Route 66 piece can be purchased on eBay; starting bid is $100, with a reserve.
Bricks 2 Pics makes other custom artwork from Legos. A gallery of its recent works can be seen here.
