Countries & Flags

The exact flag of any of 195 countries, made to move with your song: a flag waving on its pole, a round flag in a spectrum ring, the country's map tracing itself to the beat, its national colours as ribbons and fireworks, an anthem stage and a greeting card.

Launch modes

Waving Flag mode

Waving Flag

The country's flag flying on a pole: the bass lifts the wave, every kick runs a ripple through the cloth and a sweep of light crosses it on the drops.

Flag Ring mode

Flag Ring

A round flag at the centre of a spectrum ring in the national colours: the bars ring out with the music and the flag pulses on the kick.

Country Outline mode

Country Outline

The country's map filled with its own flag: the border traces itself a step on every beat, its lights glow with the mids and the capital shines as a star.

National Colours mode

National Colours

Ribbons, sparks and fireworks in the flag's colours, each ribbon lifted by its own part of the spectrum, with the round flag beside the title.

Anthem Stage mode

Anthem Stage

The flag hung over a stage: beams in the national colours sweep with the beat and confetti falls on the drops.

Greeting Card mode

Greeting Card

A card for the country's day: bunting in its colours swings on the beat over the waving flag, the country's name and your greeting.
