                put the app in an interactive VR mode.  The hand controllers will allow you to grab the origami mesh and pull on it.
                This is especially cool if you set the mesh material to <b>Axial Strain Visualization</b> so you can see how your interactions
                change the internal strains in the material.

                based on the material stiffnesses set in the <b>Stiffness Settings</b> section: more stiff settings
                require shorter time steps to solve and will slow down the simulation.<br/>

                render cycle.  If the simulation looks choppy to you, you might consider lowering this setting.
                Lowering the number of steps per render will slow down the simulation, but will result in a more smooth animation.
