As the sign says, a small dinosaur would be at home in the conservatory’s Fern Room, which is modeled on Jurassic-era plants. The experimental sound studio Florasonic composes new pieces of music every few months to enhance the environment here. For example, one piece electronically imagined the sounds of insects that might have been heard during the Jurassic age. Photo cells registered the shifting sunlight, which triggered a constantly changing chorus of chirps, whirs, and clicks. Really, truly fabulous.
