During his one month residency at Ljudmila Dmitry Morozov ::vtol:: produced a first machine in a row of a new project series called Stupa, which explores and engages topics such as gravity, stability, chaos and self-organisation. The machine itself operates in two different states - stability and chaos. As soon as the machine reaches stable phase, it changes to unsteady, chaos phase, and vice versa, keeping the machine in the continuous loop between this two stages indefinitely. The machine is a equipt with a digital gyroscope, which is providing the system information on its position in space and translates machine's movements into the sound.
