Earlier this week I was at an office in the Empire State Building when I heard singing. Cheerful songs, holidayish yet unfamiliar. The voices led me out to the lobby, where a crowd had gathered to listen to . . .

Hanukkah carolers.*

The December holidays are like that. Judaism, Christianity, the pagan Saturnalia--religions had mashup culture down cold long before Web 2.0. Pictured below is designer Sahar Batsry's fusion for the season: the Treenorah.

HT: Kottke and Kitsune Noir.

*Although I wasn't familiar with the songs, I'm pretty sure none of them were on this CD.
