American Express has teamed up with Nick Knight, a fashion photographer, to launched a real-time photo exhibit on Twitter. As part of the collaboration, the master will be capturing whatever attracts his eye around his home in West London —the focus will be made on “hidden inspiration.” The effort running under the #MySecretCity hashtag, which is also its tagline, is rolling out on July 3.

Following in the footsteps of Coke Zero’s Sweater Generator fun-packed contest, Budweiser has introduced its own sweater-themed promotion in line with the holiday knitwear season. The beer brand fosters a little revolution in sweaters production, making grannies step aside and give way to contemporary installations, powered with social media. Budweiser’s Twitter-powered knitting machine, Knitbot, creates sweaters fueled with tweeted commitments to not drink&drive.
