Smart Finger Measuring Tool

How many times have you told someone something was "about this big" holding your fingers or hands apart? What if you could do that and be precise down to a mm? Currently still in concept phases, designers Choi Hyong-Suk, Jung Ji-hye, and Yoo-Jin Park are working on making it a reality.

I don't know about you, but I think this is awesome...depending on cost. I can't say that I'd pay $100 to measure things with my fingers unless I was in a construction job of sorts...
