This is a cover of Interlude by Larry Owens, which was used as the theme song for The Joy of Painting, a show hosted by famous painter Bob Ross. Press the space bar and the painting will move (though this can make the song kind of laggy, so you might want to wait until it's done). Press the space bar again to stop the animation. It's best when viewed in full screen.
All coding and animating by Mariofan2016. The song was entirely made using Scratch noteblocks, except for the tom toms. The painting is called "Mountain Summit", painted by Bob Ross on The Joy of Painting season 13, episode 10.
