Do your Facebook postings get a lot of likes? Would you like to really feel the love whenever somebody clicks that little thumbs up? With the “Like-a-Hug” vest you can. Developed by MIT’s Melissa Chow, Andy Payne and Phil Seaton, this vest inflates and “hugs” your body a little tighter whenever you get a like. You can send a hug back by squeezing it and deflating it. Sure it might look a bit silly but it feels great to be liked, right?
