Popis:	We study the spontaneous emergence of three-dimensional motion from a quiescent, pure conduction state in stably stratified, convective flow within a triangular enclosure, which eventually self-organizes into a two-dimensional steady state. This phenomenon demonstrates that the optimal disturbance path to reach the final state is more complex than the state itself, indicating the "fastest" route involves a higher-dimensional intermediate state. This provides a model for transient spatio-temporal chaos in nonlinear dynamical systems and a challenge for classical hydrodynamic stability theory. Comment: 8 pages, 9 figures
