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 most people. Designer Sunghoon Jung has dreamed up a concept that will make drawing either one incredibly easy.
The concept overhauls a standard tape measure to include a line guide in the middle of the tape and a series of dots for anchoring your pen or pencil. And just like that you can have perfectly straight lines and a geometrically flawless circle. It doesn't hurt that the thing is easy on the eyes as well. [Yanko Design]
