Curly clouds

You can hide the outline of those gears by doing this: Right click on a gear, then hover your cursor over the word "Appearance". When another panel opens, uncheck the check box labeled "draw borders". Then save the scene on your computer. When ready, you can edit your posted scene on Algobox by uploading the scene that you edited on your computer. Now the outline of the gears will not show in your scene!
