It is Worldwide Dungeons and Dragons Gameday today, and lots of people are playing. But here is a prototype of a toy I would like to start playing with. It is built with off-the-shelf parts totaling about $350; a camera, a small projector, a cell phone, and some colored plastic or tape for your fingers. But it combines them for functionality we have never had before, and in production it would cost around $100. They are calling it the Sixth Sense, and it is the first wearable computer I have seen that turns your environment and the things in it interactive. This project is from the MIT Media Lab, one of many they are developing to invent a better future. Thanks to Technology Story for the heads-up on that one.

March is SciFi Month in Second Life this year, and one of the activities is a themed photo contest. I found a list of 7 Locations for your photo shoot over at The Examiner, which included a few favorites and a few new ones. I should probably put together a fresh list of my favorites to post here; there are a ton of them! While the name sounds like the IT department of the evil Lawyers company in Angel, Wolfram Alpha is something else, as Fast Company reports. A computer program that actually answers the question you ask, rather than throwing a bunch of links onto a page. Good to know some people are still inventing the future in interesting ways.

Happy Square Root Day! It happens only 9 times a century, when the day and month are the square root of the last two digits of the year; and this year it happens only a few weeks before Pi Day, first celebrated at the Exploratorium back in 1988. Then there is Pi Approximation Day on 22/7 of course, also known as Casual Pi Day. For fun from a different direction Reaper returns to the airwaves with the season 2 premier tonight. I didn’t expect to like the show so much when it first aired, but Ray Wise was the absolute best choice to play the Devil, and all by himself brings the show up several levels. Hope they can keep both the comedy and suspense up for another full season!
