+d arch ruler

the +d arch ruler, by tomoya yoshida, is very similar to something i have blogged about before: the bamboolarule, by baskerville studio. the idea is simple, and effective, so it's not too much of a surprise that two people would have come up with similar things.

what differs about this one is the material; where the bamboolarule gets it's name from it's material choice, the arch ruler is made from colourful plastic. it also has a nice little indentation (which you can just about make out in the top image) in the middle, for pushing down on.
