I like to shuffle through the Discovery Channel's website every couple of days. I came across an interesting little article about lasers being tuned, so to speak, to work in a way that makes the solid object it's pointed at "appear" (pun intended) to be invisible enabling the user to see beyond the solid object.
They believe that in the future they won't have to "tune" the lasers in order to do this.
Read the short article.
Pretty cool but a bit scary.
