Though it may look like it gives more than, uh, just hugs, Mark Argo's Hugms lets you give someone a friendly squeeze through your cellphone. Sent as a text message, the longer you squeeze the more of a 'hhhhhhhuuuuuuuuuggggggg' the other person gets. A short, hard squeeze gets a  'hhHHUUUUUUugg". If both people have them, the Hugms will glow a warm color when squeezed. And then of course there's the group hug, letting you get all emo with all your friends at once.
