Hanukkah Lights

Eight nights of light: a hanukkiah in a winter window whose flames dance to the mix, a spinning dreidel, a clay oil lamp and gold gelt.

Launch modes

Hanukkiah Window mode

Hanukkiah Window

A hanukkiah on a winter windowsill: eight candles in a straight row and the raised shamash, each flame dancing to its own part of the mix while snow falls past the glass.

Dreidel Spin mode

Dreidel Spin

A dreidel spinning on a polished table, its four letters turning past as the mids drive the spin, with the candles glowing out of focus behind.

Eight Nights mode

Eight Nights

Eight glass pillars and the taller shamash as an equalizer; the song lights one more night at each new section, from the first night to the eighth.

Oil Lamp mode

Oil Lamp

A clay oil lamp, the light that lasted eight days, throwing a fan of rays that follow the spectrum, with eight small lights kindled along the ledge. Calm, for spoken word and podcasts.

Silver Snow mode

Silver Snow

Out in the snow, looking up at a window where the hanukkiah burns; the flakes drift on the mids and glint silver on the highs.

Gelt Shimmer mode

Gelt Shimmer

Your cover art set in a gold coin ringed by a circle of beads that follow the spectrum, with foil-wrapped gelt tumbling through the light.
