The clever guys over at Koala Tools have a new ruler – but forget straight. This is a rule for circles (how did anyone not think of it before). It doesn’t just draw them, it measures them in ways you can get really geeky about. They are launching this through Indiegogo and I’m a backer – I chose the package that includes their versa ruler (image below) which I’ve had my designer eye on for a while). It makes me smile that technology brings us tools that we can create with (both in the funding and in the design).
