Diwali Lights

The Festival of Lights in six shots: clay diyas on courtyard steps, a rangoli that draws itself, swaying star lanterns, sparkler trails, courtyard fireworks and a marigold-framed doorway.

Diya Row

Clay lamps line a courtyard's steps: each flame is one band of the mix, every beat lights the next lamp along the row, and each new section lights another step.

Classic Studio

Rangoli

A symmetric rangoli draws itself across the courtyard floor as the song plays, ringed by diyas that carry the spectrum; each beat sends a ripple of light through the pattern.

Classic Studio

Lantern Sway

A star-shaped paper lantern sways over the rooftops: the bass swings it, beats flare its light, and lanterns and strings of bulbs around it each glow with their own band.

Classic Studio

Sparkler Trails

Sparklers write glowing loops in the dark, their trails tracing the spectrum; highs throw sparks, beats burst the centre sparkler, and each section draws a new figure.

Classic Studio

Courtyard Fireworks

Flower-pot fountains spray gold sparks across a courtyard while distant fireworks open over the lit town; the bass sets each fountain's height and the loud sections fire the shells.

Classic Studio

Marigold Toran

A marigold garland frames a lit doorway with your cover art inside: each hanging strand is a band, and every beat runs light down the next strand and shakes petals loose.
