SUNDAY SHOW & TELL
vol.83

This week, we bring you a rather international smattering of fascinating projects. First up, South Korean artist Young Deok-Seo spends months welding and forming discarded bicycle chains into striking sculptures of the human form. Truly, this is powerful repurposing.

Second, Vietnamese architect Vo Trong Nghia designed three 22-story buildings in Ho Chi Minh City that each have a giant roof garden. The roofs are all connected by suspension bridges, making the completed structure a giant linear garden in the sky. Now that's what we call green architecture!

Finally, Donhou Bicycles, a London-based company, set off to construct a bicycle with a chain ring big enough to achieve pedaling speed of 80mph. Theirs is a great story of determination and innovation.
