Portable music player with synchronized transmissive visual overlays

A method for providing music-responsive transmissive visual overlays that augment a user's view of the real world, the method comprising:

• providing a transmissive display for displaying visual content such that a user perceives the displayed visual content as a real-time visual overlay upon the user's view of the real world;
• functionally coupling the transmissive display to a processor associated with a portable media player;
• providing a music responsive visual overlay program including instructions executable by the processor for modulating the visual content displayed upon the transmissive visual display in apparent time synchronicity with an audio outputting of a playing musical media file;
• and,
• functionally coupling an audio processing subsystem to the processor for audio outputting the playing musical media file to the user.

A computer program product embodied in a tangible form comprising instructions executable by a processor to:

• play a musical media file stored in a memory coupled to the processor;
• generate an audio output from the play of the musical media file;
• generate a visual content modulated in apparent synchronicity with at least one varying characteristic of the generated audio output for display upon a transmissive visual display coupled to the processor;
• output the modulated visual content to the transmissive visual display such that a user perceives the displayed visual content as a real-time visual overlay upon the user's view of the real world which varies in apparent time synchronicity with the audio output generated by play of the musical media file.
