We all have those days when life seems to be grey and dull, and everything around us becomes weary. A Dutch Vollaerszwart art studio are nowhere even close to being short of ideas on how to crack some smiles. One of their outdoor art installation, called Let’s Stick Together, surely didn’t go unnoticed in the streets of Roterdam, Holland. The buildings and the sidewalks blossomed in pink, as 50 000 fluorescent pink stickers were put up all over the place. This was part of the De Wereld van Witte de With art festival, and just one of many other creative installations by the Vollaerszwart.
