If like me you grew up with the original Star-Trek and following suites, you must have some point thought that the coolest gadget of all time was the famous tricorder. Well a MIT group is bridging the gap between the tricorder and an iPhone with some cool image processing algorithms. See this Eulerian Video Magnification and in particular the movie as you scroll down.
One day this might be the coolest father’s day gadget (or App) 😉
