Every day on twitter I look for something Obscure and Interesting (sometimes it turns out to be obscure and worrying). Today, through links I found this. It belongs to the Obscure and Wondering category.
Alesandre Farto aka Vhils – artist – he creates portraits by scratching paint off building walls.
Lovely stuff. You can view more on his website here.
Obscure and Interesting is a form of mental yoga. I recommend doing it at least once a day.
