After decades of development, virtual reality (VR) systems for the masses seem finally just around the corner. This paper presents a practical opportunity for the use of VR in a botanical museum context using a popular game engine and an already available developer version of a head-mounted display. The authors describe the creation of the VR exhibit, a fantastic landscape accessible with roller coaster ride amidst an impressive glasshouse with lifelike 3D plants. It also examines the merits and limitations of this VR diorama including some preliminary results from user feedback.
