BXL swings in the cracks, which for now has only a Facebook page (damnit!) describes itself as:
Collective who up-cycles waste (scrap wood, discarded domestic furniture, …) into parasite interventions with the aim to vitalize public spaces.
For obvious reasons and relations to my uHbench project, I immediately fell in love with this group and totally support their vision, so well expressed in this sentence (again taken from their description):
The insertion in some strategic but forgotten urban space in European cities of small design interventions will have the multiple intentions of provoking a reaction both from citizens and from the institutions and at the same time revitalize a blind corner of the city.
