Last week traffic was bought to a stand-still outside Brick Lane’s Rokit, as crowds gathered to play Tweet This Window, a guerrilla fundraiser organised by ENSO’s sister studio, Those, for the Cafédirect Producers Foundation (CPF).

Tweet This Window for Cafédirect Producers Foundation

As part of the CPF’s commitment to engaging new audiences, Those used their Woodpecker drawing system to turn Rokit’s windows into an interactive Valentine’s Day message board.

For a small donation, the public could tweet their Valentine’s Day messages to @TweetThisWindow and watch the Woodpecker decorate Rokit’s window for their loved ones to see. Across the weekend, hundreds of locals, tourists and shoppers stopped by to participate in the surprise project, raising money and awareness for the CPF.

With Tweet This Window a success, the Woodpecker drawing system is set for a full launch in March 2015. For more information, check out
