Seung Jin Yang’s Blowing Series makes use of many varieties of optical illusions.

First, there’s the illusion that these extravagant chairs are actually balloons. Then, the magical reveal that, yes, they really are.

But the biggest trick here is the assumption that balloons are fragile, weak. Says Yang, “The balloon provides an empty space. Therefore, if I only apply epoxy on the outside, I have a sturdy structure. It’s like a block of Lego.”

Everyone knows that Legos can transform into just about anything. So it is with Yang’s balloons. The spontaneous shapes they inhabit become the building blocks for this very colorful and enchanting furniture, instilling some much-needed childlike wonder into an ostensibly mundane object.
