Rarely does anyone see true innovation in the tools used to build software. In the software world, developers use software editors to create software. These editors are called IDE (Integrated Development Environments) and most all work and function the same. I have to take my hat off to Chris Granger and his Light Table project, he's basically taken a novel approach to usuability, reading and interacting with code. I hope that his work can become the standard ide for clojure. First check out his video. I am supporting this project on Kickstarter and hope you will too. "Support Light Table"
