Last year, Michael Bosanko created what is reportedly the world's largest ever light painting. This video shows how he did it.
Having commandeered a 3250sqm aircraft hangar in Coventry, UK, Bosanko set to creating a continuously drawn, Halloween-themed light painting. To achieve the result, pictured below, the shutter of his camera was open for a staggering 60 minutes. With so much room for error, the result is amazing -- and it's fascinating to hear him talk about how he achieved it.
