Hi all,
A very simple experiment can make us relax with beautiful scene
Using a kaleidoscope, and let a LED source to emit light with red color to the back side of the kaleidoscope. You will see many images with very beautiful scene
The light make the patterns created by the kaleidoscope turn into red, with blinking effect
We can improve with green color LED, or combine both red and green
