Forsta is a unique green concept speaker design using a bamboo. Growing a bamboo to serve as the speaker is the concept of the Forsta. Prior to the growing process, a speaker is installed inside the bamboo that serves as the sounbox of the speaker. As the bamboo grows the better sound quality it can provide, and the bigger the soundbox is, the reacher is the soound produced. I find this concept pretty cute, but I doubt it would come into reality. We all know that a bamboo has the ability to grow higher making the eco-ceramic based unable to handle anymore.
