The flagship building on Facebook's expanded Menlo Park headquarters officially opened for business this week.
The 430,000-square-foot building was designed by award-winning architect Frank Gehry and built over a three-year period.
Gehry is known for his unconventional aesthetic, using surprising angles and metal materials that have a strangely undulating effect.
We've rounded up some of his most famous works here.
Facebook employees started moving into their newly expanded headquarters last week. Totaling more than 430,000 square feet, it's a massive structure that will ultimately hold about 2,800 people.
Most recently, Gehry designed the Dr. Chau Chak Wink Building, a structure on the University of Technology's campus in Sydney, Australia. It's known by some as the "crumpled bag building."
The colorful Biomuseo of Panama City was also finished in 2014.
