#5 Piano and Violin Building, China
Patently inspired by music, this building was built in 2007 and was meant to promote a newly developed area. It is beautiful during the day and spectacular at night, as it uses bright lights.
#6 Nautilus House, Mexico
The Nautilus House in Mexico is a shell shaped house built by Javier Senosiain, a Mexican architect in 2006. Meant to focus on the harmony of nature, it kind of gives us a feeling of a Hobbit House on acid.
