The San Diego Botanic Garden has a very cool bamboo garden. This is a place worth visiting. The entrance is a bit steep at $14, but ask about a student discount.
Not long ago, a student of mine took an active interest in bamboo as a building material and is now studying alternative architecture. He pointed me in the direction of this TED talk, which is fascinating. I love the fluid lines of the buildings. For more inspiration, check out the GreenSchool of Bali.
