Messaging apparatus for wearable items

A non-transitory computer-readable medium comprising program code that is executable by a controller for causing the controller to:

• determine a frequency at which to flash a light source based on one or more characteristics of a movement of a wearer of the light source, the light source being adapted to perform a flash operation involving flashing the light source;
• determine whether to perform the flash operation using a machine-learning algorithm;
• and
• in response to determining that the flash operation is to be performed, trigger the light source to perform the flash operation at the frequency to generate at least one visible element for display to a viewer, the at least one visible element having a different shape than the light source.

A method comprising:

• determining, by a controller, a frequency at which to flash a light source based on one or more characteristics of a movement of a wearer of the light source, the light source being perform a flash operation involving flashing the light source;
• determining, by the controller, whether to perform the flash operation using a machine-learning algorithm;
• and
• in response to determining that the flash operation is to be performed, triggering, by the controller, the light source to perform the flash operation at the frequency to generate at least one visible element for display to a viewer, the at least one visible element having a different shape than the light source.
