Your project is coming along beautifully! The cylinder shape and the various cutouts are going to create a wonderful shadow pattern when illuminated. Here’s how to take your project to the next level:

1. Add a Light Source Inside: Place an LED inside the cylinder or use a flashlight app on your phone to create an inner glow. Make sure the light source is stable, so it doesn’t move around inside the box.
2. Experiment in a Dark Room: Take your project into a dark space and use a flashlight or phone light from outside to shine light through the holes. Try different angles and distances to see how the shadows change on the walls.
3. Capture the Effect: Once you find a setup that gives the best shadow pattern, take a photo or video to capture it! You can even experiment with colored light or translucent paper over some cutouts to see how it affects the shadows.

You’re on the right track to creating something really unique and dynamic!
