Using four sets of Hexadecimal color codes, two new sliders and new look for the Start/Stop button that reflects the color used. Why the images are not changed simultaneously with the animation color set?[br]Actually slider b select the color list, and Color list is just accessing the color list set by Slider e.
In the assembly of the video, in the first part , I separated the parts by color. In the second part I used iMovie rotation tool, to obtain a horizontal version of the animation (Could be done in GeoGebra, but needed much more work and knowledge on my part). in the third part as usual , the music sheet (PDF Below) can be followed. (Music still needs some corrections, I may work out another version).[br][br]I could not add URL to the two gg files. Any idea why they are transformes in the format xx@yyy ?[br]Youtube : Orchestral Kit and Marimba : [url=https://youtu.be/BB3txt2clKQ]20210313 MG Vasarely Music Toy[br][/url]Youtube : Piano and List for [url=https://www.youtube.com/playlist?list=PLHsHfKHL2zdFCiVobegeGNXDHTfpHd4cR]milanofff's animated Applets[/url]
