landscape waveform - array size

[1 Reply]

- Forum: Core Library Questions
Can someone help me limit the array, so I can get something like in this video at 0:51s:
http://vimeo.com/4289626

I'd like to have the landscape with a limited size, so the shapes keep shifting and the older ones are eliminated

What's the best way to create a rounded rectangle with the possibility of using only the stroke?
