Last night a 3-year old woke up crying in Massachusetts, caught in a nightmare he couldn’t reason himself out of. Vulture Bytes and friends came to the rescue, but he wouldn’t stop wailing. With nowhere else to turn, we picked up the iPad. Two minutes later, Tangled was streaming through Netflix, and a minute after that the kid was quiet. It’s the kind of thing that reminds you why all this technology is worth it. Speaking of! This week: turning yourself into an avant-garde artist, accessories to help store your headphones, a way to make use of your fidgeting, a YouTube dance-party-maker, and throwing your own Riverdance.
