Using #clojure and membrane, I made a little tool that makes interactive notes/calc tools for my design and engineering needs. Should be useful to build up a small library of simple calculators :)

Make your code more tangible
#clojure #clojurescript #svg

Here's an example of using #clojure to define a data model for CAD geometry and operations. From that model, I can create a STEP file via #FreeCAD and also view/export a meshed solid via #OpenSCAD

Here's a fun #badspreadsheet demo. Use a set of draggable points to sketch shapes over an image. Simple pieces, a way to view SVG, a way to get the position of every point, and a way to layer cells over one another. Add some #clojure and you've got a powerful tool :)
