A new smart bracelet called Tago Arc can't notify you of incoming messages or monitor your activities, but it has already raised more than its $40,000 goal on Indiegogo. Why? Because it has the potential to become a high-tech fashionista's best friend, provided it works flawlessly. See, you can easily swap the design on the Tago Arc's e-ink screen, and since that screen takes up most of the accessory, you're effectively changing the jewelry's whole look. If you're wondering, yes you can create your own designs to come up with a unique bracelet for each outfit, but you can also buy images from the accompanying app for around $1 a pop.
