I often need a cloud shape in PowerPoint to draw a network diagram. The standard PowerPoint cloud is not very pretty. Here is a way to construct a new cloud shape in the style of the logo of the iCloud service by Apple.

Takamasa Matsumoto originally discovered how the iCloud logo is infused with golden ratios. If you use these proportions to draw some basic shapes in PowerPoint, you can combine them using the shape union command (on the Mac right click the selected shapes, go into grouping and select union). You see that I use 2 extra rectangles to fill up the shape.

Here is the final result compared to the standard PowerPoint cloud shape, with heavier lines around the shape.
