The Visions Project K. 1 is an interactive video installation consisting of a volumetric device that allows visualization of 3D objects and their interaction with the user in real time. Objects are projected onto a pyramidal structure with an LCD monitor, and due to the special geometry of the structure, they look like real 3D objects floating inside the pyramid for any observer from any direction. The modular design of the components of the structure enables the user to build his or her own device DIY (Do It Yourself).
