Horseradish fire alarm and an Etch-A-Sketch

Here's to thinking "outside the box"- Japanese researchers are testing a smoke alarm that alerts people using the smell of horseradish. Reportedly, those with hearing impairments were "partiularly quick to wake up."

Though it said that all subjects (14) woke within 2 minutes, I don't want to wait that long if there's a fire in my house.

On another note, engineers have rigged up an Etch A Sketch to work with a computer mouse. Sounds fairly complex, but follow the links in the article if you think you'd like to give this project a crack. <LINK>
