Tis the season for agency holiday cards, and Wieden + Kennedy London does not disappoint with this little nugget.
The agency set up a "Choir of You" installation outside its Hanbury Street office, which invites passers-by to stand outside the window and open their pipes. They will see their likeness multiplied in the window depending on how high they raise their voices.
