Add this line of code after line 187 in ViewController.swift and the clouds will start their animation at a different y position.  
`cloud.frame.origin.y = CGFloat.random(in: 100..<self.view.frame.size.height-200)`

You could do the same with the speed to create the illusion of depth. Replace line 182 with:  
`let cloudSpeed = CGFloat.random(in: 30.0..<120.0) / view.frame.size.width`
