For those who actually unsheathe the S Pen from their Samsung device from time to time (unlike yours truly), there's now away to flaunt your stylus-ing prowess in public. The company has just launched PEN.UP, a social networking app dedicated to digital artwork from suitably-equipped Galaxy devices. Like any good sharing app, you can set up a personal feed containing your own sketches, group them thematically and follow and like others. For those who think drawing is a competitive sport, there's even a hall of of fame where members can vie for champion artist honors. So, if you're looking to get your S Pen on (and have a supported device), hit the source.
