Now let's add an image. Even though LEDs like this are more about creating interesting

light patterns than displaying video, images can be super useful as building-blocks for these

light patterns. It may be helpful to think about images as if they're textures or color look-up

tables.

In this case, we're creating a particle system that uses many copies of the same image to

create a moving field of light. The light will look like expanding wavefronts, and each particle

is a ring of light that we can tint however we like.

I made a simple ring texture in Photoshop. You can make your own, or save a copy of

mine. If you do, make sure to save the image as a PNG file.
