This is an animation that uses the historical Stretch block. It will work under Scratch 3.0 but is so much more interesting if you download it and run it under Scratch 1.4 To Play: Step One: Use this link to download the program: https://forkphorus.github.io/sb-downloader/?id=621465314&type=sb Step Two: Use Scratch 1.4 to load and run the download from step 1 (which will be called: 621465314.sb) Sorry that there is no music but Scratch would not let me share from Scratch 1.4 when there was a sound file in the project.
I just tinkered around with the graphic effects, including the historical Scratch stretch block until I made something interesting.
