Drawing a perfect circle is maybe the hardest thing one can do with a pen in hand. A straight line, while much easier to accomplish, is still a chore for some. With that in mind, designer Sunghoon Jung has dreamed up a concept for a tape measure that not only has a line guide in the middle of the tape, but also a series of dots you can anchor your writing instrument to so that you can scrawl a geometrically perfect circle. It doesn't hurt that the thing is easy on the eyes as well. [Yanko Design]
