So this wonderful thing showed up in my inbox. Belgian artist and illustrator Stefaan De Croock aka Strook pressure washed this awesome piece on a mossy wall outside of the STUK art center in Leuven. The non-destructive mural is all that more impressive considering it was done completely improvised without a sketch for reference, and it was the first time he’d used pressurized water to boot. Thanks Strook for sharing your work with Colossal!
