#PoweredByTweets:The Challenge

See winning entries from nationwide design competition #PoweredByTweets organised by the London Design Festival with Twitter. Launched in April, entrants were invited to come up with an idea that either solved a problem using Twitter or created something beautiful using Twitter data.

There were six winners in total and each of the winning entries has been built by Pixie Labs (@PixieLabs), ready to appear as part of London Design Festival at Somerset House.

Winning entries include a pigeon air patrol to monitor the quality of air and report back in real time on Twitter and a beautiful interactive art piece that uses Twitter to campaign against the law that bans gay men from becoming blood donors.
