Artist David Mesguich (previously) has been creating large geometric sculptures that he installs in locations around Belgium and France, blurring the lines between street art and fine art. The pieces are displayed in public areas and aren’t made to be sold but are instead donated to the city. Of his most recent work, PRESSURE 1.0, he remarks:

The story of “pressure”—it’s the story of people who are on the fence, in between worlds, those who are both on the inside and on the outside. My inspiration came from two sources: a family history that steeped me in a violent, carceral universe during my youth and more than 10 years of trespassing with graffiti.

Mesguich has several other pieces you can see on Behance and on his website.
