Here's the video of one of their latest projects, Vegetal for Vitra (2009):
Another two famous objects by the Bouroullec Brothers are:
Algues for Vitra (2004):
They say: "Twigs and Algues are 2 projects that lead down the same path. The common idea is to approach architecture from the millimetre. Or how the repetition of a same motive brings to a larger scale".
Cloud Modules for Cappellini (2002):
Clearly, nature inspire them.
