Noise Generator! Go to: https://turbowarp.org/1061880415?fps=60&turbo to use this. Change the resolution and speed before using this. It is recommended that you set the variable to 5. Use a & s to show and hide the variable. If you DON'T wanna go to the link for this, then play this project as normal, but use turbo mode.
