This is a weekend project I've been working on with a few friends. The goal is to build a prototyping tool that lets you express your ideas in a sharable format. It's built with React.js/Om, datascript and Datomic. They've worked out really well for us. I'm amazed at how often things that seem difficult to build turn out to be fairly easy. Last night I leveraged Datomic's transaction model (implemented by datascript) to add Emacs-style undo in about 30 minutes. I'm very curious to hear any feedback you have. The url I posted tries to group people in buckets of 10 to show off the collaboration aspect. If you want a page to yourself, just click the "New Document" icon on the left.
