Back in January of this year Belgian street artist Roa was invited by Unit-44 for the third instalment of the White Walls Project in Hoults Yard, Newcastle. Many of you will have already seen photos of ROA's street art piece ‘The Four Horses Of The Apocalypse’ pictured above but the guys at Unit-44 have just posted this time-lapse video of the artist at work on this huge piece.
