Use arrow keys to adjust speed. Press D to show/hide dual. press R to show/hide rings. Version 2 has on screen arrow controls (for tablets and smartphones) Version 3 has X-axis rotation (sorry, no way to edit rotation speed right now) Version 4 has ring show/hide (yes, it works on mobile) Version 4.5 fixed proportions
thanks to @JimmyC for some of the scripts and the original "Octahedron Ver. 2" project. thanks to @pusheen4robot for THE IDEA OF X-rotation. (there is only Y-rotation in version 2)
