Sibling Bridges is a rather interesting portfolio.
Each piece is intended to bring connection to the next piece. All works in this series are connected to each other and form a complex network of trees. Along the way, new vectors (locations on earth) are added, locations that would benefit from these connections. At each new location, the next vectors are added.
So from Venice to Monteria, to Fort Lauderdale etc.
The cost of each piece is 4 times the cost it takes to travel to each location at time of purchase.
