My first project idea was to create a set of RGB keyboard profiles that could react to how a user types. For example, pressing a key could result in the key lighting up and then slowly fading, or pressing a specific key can cause the rest of the lights on the keyboard to ripple in response. The concept is simple but creating keyboard profiles requires a specific set of software that while powerful, can be confusing and will present a challenge in using the software to its full potential.
My second idea would be creating a prop that uses light, like a wand or staff. The prop would be created of a light sculpting material like paperclay, and would have LEDs wired internally that can be switched on or off, and arranged in order to create a visually interesting design. The resulting piece could be inspired by an already existing design, or a new concept. Finding some specific parts for some designs may be difficult, and it will be important to avoid a design that is too simple.
My third idea would be to create a lantern- this could range from a more complex design, to something simple but dynamic, like a lantern that changes color depending on the weather. The lanterns would probably use LEDs as a light source, but in more dynamic versions would most likely be supplemented with an arduino or raspberry pi that can process the data needed.
