The British Museum
A day trip to London ended up at the British museum, it's huge, and impossible to honestly finish it in one visit. The section on "Africa" was the best, and within it the Throne of weapons by Mozambican artist Cristovao Canhavato (Kester). The chair sculpture is made from decommissioned weapons from the civil war in Mozambique.
A detailed post on the art work I found inspiring is here.
