Easter & Spring

A spring meadow at sunrise: painted eggs nestled in new grass, flowers that open with the music and petals on the breeze.

Launch modes

Spring Meadow mode

Spring Meadow

A row of painted eggs nestled in new grass at sunrise: each egg rises with its own band, the tulips behind them open with the bass, and the kick hops one egg at a time.

Egg Patterns mode

Egg Patterns

Three large painted eggs turning slowly on a straw nest; their geometric bands paint themselves on with the spectrum, and each kick wobbles the next egg.

Blossom Bloom mode

Blossom Bloom

One spring flower opening as a circular spectrum against the rising sun, with a new ring of petals unfolding at every section of the song.

Sunrise Hill mode

Sunrise Hill

Calm dawn rays over misty hills, slow and gentle: made for spoken word, worship music and quiet songs. The sun climbs as the song plays.

Petal Breeze mode

Petal Breeze

A stream of blossom petals carried on the spring breeze, with butterflies in the light; the stream swells with the spectrum and gusts on the kick.

Basket Garden mode

Basket Garden

Your cover art standing in a woven basket of tulips, with painted eggs peeking over the rim; the flowers rise and open with the music.
