It's not such much a literal tattoo as an electronic interface implanted beneath the skin:

The basis of the 2x4-inch "Digital Tattoo Interface" is a Bluetooth device made of thin, flexible silicon and silicone. It´s inserted through a small incision as a tightly rolled tube, and then it unfurls beneath the skin to align between skin and muscle. Through the same incision, two small tubes on the device are attached to an artery and a vein to allow the blood to flow to a coin-sized blood fuel cell that converts glucose and oxygen to electricity. After blood flows in from the artery to the fuel cell, it flows out again through the vein.

On both the top and bottom surfaces of the display is a matching matrix of field-producing pixels. The top surface also enables touch-screen control through the skin. Instead of ink, the display uses tiny microscopic spheres, somewhat similar to tattoo ink. A field-sensitive material in the spheres changes their color from clear to black, aligned with the matrix fields.

The tattoo display communicates wirelessly to other Bluetooth devices - both in the outside world and within the same body. Although the device is always on (as long as your blood´s flowing), the display can be turned off and on by pushing a small dot on the skin. When the phone rings, for example, an individual turns the display on, and "the tattoo comes to life as a digital video of the caller," Mielke explains. When the call ends, the tattoo disappears.

Healthcare Robotics is hard at work developing a robot that will interact with the world at the click of a laser pointer. Simply point at an object, and the robot will go and pick it up.

In our object fetching application there are initially virtual buttons surrounding objects within the environment. If the user illuminates an object ("clicks it") the robot moves to the object, grasps it, and lifts it up. Once the robot has an object in its hand, a separate set of virtual buttons get mapped onto the world. At this point, clicking near a person tells the robot to deliver the object to the person. Clicking on a tabletop tells the robot to place the object on the table. While clicking on the floor tells the robot to move to the selected location.

One obvious application would be to assist people with limited mobility. Click the link for a video of the robot in action.

Star Sports - Theatrical Trailer

Every year, Atom Films hosts a contest for Star Wars-themed fan films.  There are several categories and this film, Star Sports Theatrical Trailer, won the Best Parody category.  It imagines the Star Wars story as a series of high school sports, such as the Battle of Hoth as a game of dodgeball (I think). You can view all of the winners at the link.

James May of the British television show Top Gear is planning to build a full-sized house out of LEGOs:

On Friday, more than three million Lego bricks were delivered to the vineyard in preparation for the task.

Denbies marketing and business development manager, Jeanette Simpson, said: “The millions of bricks came all the way from the Czech Republic. The house will be life-size with a staircase, toilet and shower.”

It was big enough to provide 1,500 servings:

Measuring 12 inches tall and 24 inches wide the cupcake weighed 150.7 pounds and used 15 pounds of fudge filling and 60 pounds of yellow icing.

Makers cakes.com created the cake as part of celebrations for the SpongeBob SquarePants' 10th anniversary at the Minneapolis Mall of America.

An adjudicator from Guinness World Records was on hand to inspect (and sample) the cake before declaring it the world's largest cupcake.

The Rubix Cube has confounded us for years. Maybe the sandwich version of this puzzling brain teaser will do the same. The Rubix Cubewich contains cubes of pastrami, kielbasa, pork fat, salami, and two types of cheddar.

Jen Hui Liao created a machine that will take a picture of the user, and then guides his/her hands to draw the image on paper. Liao says:

I found some the relationship between human and machine are amazing and could be horrible (like this one that shows how we human invent machines then put human inside to it to manufacture goods), The final object - A machine is a miniature of what I understand through the process of research, and the aim of the machine is to let people have a chance to feel the condensed process of how we generate our self identity from external point of view as from the society, which is a big machine we all in.

Maybe this fellow doesn't have a car on which to put his bumper stickers, or he just wants to communicate with people walking behind him.

If you had bumper stickers on the back of your shoes, what would they say?

Craftster member enemyairship created this 7 by 7 foot rug of Mario in raccoon form:

He's made of 386 granny squares, each one representing 1 pixel (3.5" each) that makes up Raccoon Mario. I learned to crochet in February by watching youtube videos and recently watched another video for granny squares and got started on this project right away. I had originally thought that it would take me over 1 month to complete if I made about 10 granny squares per day.

This is why I will never get a tattoo:

TAMPA - It wasn't particularly hard for the victims of a Riverview home invasion to identify the burglar. He was the only one with an outline of the state of Florida tattooed on his face, authorities say.

In addition to the Florida tattoo, Sean Roberts also has the words "Crazy Cracker" written or tattooed on his head, Hillsborough County sheriff's spokesman J.D. Callaway said.

And to think that if he had chosen a rectangular state like Wyoming or Colorado, he could have escaped.

Il Gatto is a short film by Peter Atencio.  It's about the love that a woman has for her kitty cat/sensei and her quest for vengence against the man who accidentally drove over it.  It seems modeled on Quentin Tarantino's Grindhouse films.  Run time: 5 minutes.

Engineering students at Virginia Tech have built a car that can be driven by the visually impaired. The vehicle is equipped with laser range finders and a semi-autonomous computer that helps direct drivers around a course that they can't see:

The steering wheel is hooked up to a distance monitor that gathers information from laser range finders, and it uses voice software to tells the driver how far to turn the wheel. For example, the monitor will tell the driver “turn left three clicks.” As the driver does that, the monitor makes three clicking noises.

A vibrating vest provides cues to follow when accelerating and decelerating. The vest vibrates in different places — the back, the belly and the shoulders — to convey different commands. When the entire vest vibrates, it means, “Slam on the brakes!”
