Palimpsest
Palimpsest is a very simple HTML5 Canvas drawing application. It is written in ClojureScript and can run in a web browser without any backing server.
The application optionally supports smoothing lines drawn by the user using the Bezier curve-fitting algorithm described in “An Algorithm for Automatically Fitting Digitized Curves” by Phillip Schneider.
The palimpsest source code is hosted on Github. You can find a live demo on Github Pages.
