Seriously love me some Ai Wei Wei installations. Here is a recent(ish) one titled "Bang". 886 3 legged stools suspended at the 2013 Venice Art Biennale.
The inspiration for this piece comes from the common practice of Chinese families to have one of these hand made wooden stools in their household. Most families had at least one of these and they were passed down generation to generation. But now, due to the influx in population and the huge economic boom in China, many families have swapped out for plastic and metal alternatives for style/convenience. I like to think of this piece as an odd to times past. Over here in the Western world we are not as aware of the changes taking place in China and just how quickly it is happening. If you have some free time take a look at some websites and news reports dedicated to this topic. It is pretty interesting, in my opinion.
