The holidays are all about eggnog, ugly sweaters and disconnecting from the internet just long enough to reassure the family you still care. For those of us with web separation anxiety, the folks at MAKE have hooked us up with an easy way to stay hip to incoming emails -- by connecting the holiday fir to the Internets. It works as such: using an Arduino and PHP script, the tree will check for incoming emails and light up if the number has increased. The set-up can be tweaked based on your most valued type of alert like YouTube comments, texts or changes in the weather. To the family, it will look like unparalleled holiday cheer rather than your cue to ditch the sing-a-long and get back to Gmail. Check out the video after the break.
