Kinect Hack Makes Shadow Puppets Real(ish)

The Microsoft Kinect has been selling like hotcakes, and geeks have been using it to do amazing things. The best I've seen so far is this "shadow puppet" app created in one day by exhibit designers Emily Gobeille and Theo Watson using free, open-source drivers for the Kinect. They actually connected the Kinect (ahem) to a Mac and wrote some code in order to make this work.

This app tracks "the elbow, the wrist, the tips of your fingers, and your thumb" in order to turn a shadow puppet gesture into a realtime animated bird (complete with squawks!) projected on the wall. Wait, what? Does this mean that our kids will never learn the fine art of shadow puppetry?? Probably. And I, for one, welcome our new animated bird shadow puppet overlords. BEHOLD:

For more info (and links to download the underlying drivers yourself), check out this Vimeo page. Gobeille and Watson make art and museum installations, so they're familiar with interactive art. But I'm guessing that installation-making process just got a lot more awesome.

Make Spreadsheets a Whole Lot Easier With This Excel Trick

While data nerds may love a good spreadsheet, many office workers open Microsoft Excel with a certain amount of resistance. Inputting data can be a monotonous task. But a few tricks can make it a whole lot easier. Business Insider has a new video highlighting one of those shortcuts—a way to create a range that changes with the data you input.

Dynamic named ranges change and grow with your data, so, for instance, if one column is time and another is, say, dollar value, the value can change automatically as time goes on. If you do this, it's relatively easy to create a chart using this data, by simply inserting your named ranges as your X and Y values. The chart will automatically update as your range expands.

It's easier to see in the program itself, so watch the full video on Business Insider. Microsoft also has its own instructions here, or you can check out this video from the YouTube channel Excel Tip, which also has dozens of other useful tutorials for making Microsoft Excel your hardworking assistant.

History
Marshall McLuhan, the Man Who Predicted the Internet in 1962

Futurists of the 20th century were prone to some highly optimistic predictions. Theorists thought we might be extending our life spans to 150, working fewer hours, and operating private aircrafts from our homes. No one seemed to imagine we’d be communicating with smiley faces and poop emojis in place of words.

Marshall McLuhan didn’t call that either, but he did come closer than most to imagining our current technology-led environment. In 1962, the author and media theorist (who is the subject of today's Google Doodle) predicted we’d have an internet.

That was the year McLuhan, a professor of English born in Edmonton, Canada on this day in 1911, wrote a book called The Gutenberg Galaxy. In it, he observed that human history could be partitioned into four distinct chapters: The acoustic age, the literary age, the print age, and the then-emerging electronic age. McLuhan believed this new frontier would be home to what he dubbed a “global village”—a space where technology spread information to anyone and everyone.

Computers, McLuhan said, “could enhance retrieval, obsolesce mass library organization,” and offer “speedily tailored data.”

McLuhan elaborated on the idea in his 1962 book, Understanding Media, writing:

"Since the inception of the telegraph and radio, the globe has contracted, spatially, into a single large village. Tribalism is our only resource since the electro-magnetic discovery. Moving from print to electronic media we have given up an eye for an ear."

But McLuhan didn’t concern himself solely with the advantages of a network. He cautioned that a surrender to “private manipulation” would limit the scope of our information based on what advertisers and others choose for users to see.

Marshall McLuhan died on December 31, 1980, several years before he was able to witness first-hand how his predictions were coming to fruition.
