Super cool! Says a related article, “The Audio Spotlight system uses nonlinearly propagating ultrasound to create highly directional beams of sound in mid-air, which can be “shone” and “directed” much like light.”

This could be used to freak so many people out.

30-Day Meme – Day 8: Describe the style you had 10 years ago.
Haha, what is this “style” you speak of? Let’s see…ten years ago was 2001, so I was in 7^th grade. I wasn’t quite as colorful as I am nowadays, but I still wore a lot more color than my peers. I remember being compared to Phoebe from Friends with respect to my clothing…though I wouldn’t really know how accurate this statement is, ‘cause I’ve never seen Friends. So I guess my style is the same as it is now, only subdued.
