The Free Form Ruler from Monocomplex combines a ruler and a pen to create an unstoppable measuring/drawing force. The Free Form Ruler is a pen designed with an internal ruler that measures how long your lines are.
The Free Form Ruler has an adjustable digital display that shows measurements in either centimeters, millimeters or inches. The Free Form Ruler would be particularly useful for fashion designers and contractors, who often find themselves needing to make accurate on-the-spot measurements. As with all awesome designs, the Free Form Ruler is unfortunately still a concept. Hopefully Monocomplex will find a way to start cranking out Free Form Rulers like there's no tomorrow. I don't want to live in a world that requires both a pen and a ruler to make accurate measurements.
