I tried to create these shapes several times ago without success. I tried with illustrator and a blurry shape that I deform with "Envelope Distort" > "make with mesh" but the result isn't very convincing. I'd tried with photoshop but there isn't a tool like the one in illustrator…
Can you help me ?
