Click the flag and a prism will constantly be drawn where the crosshair is. Click and drag the crosshair to move it. If this causes lag, set the lag-reduce slider to 1 and it will only be updated when you press space. Use the variables along the top to stretch and turn the prism and the variables along the bottom to change the colour of various parts of it.
