A couple of Swedish designers have launched a kickstarter to fund a ruler that is intended to bridge the gap between the digital and physical world. It has measurements for inches, centimeters, pica and pixels. Thanks to a cut down the middle, you get all four edges on one side. That cut is precision machined to fit most pen tips perfectly. The way the lines are drawn, you can also create a perfect 90-degree angle from another line by lining it up from one side to the other. They’ve blasted past their goal and you can still back it for about $20.
