These are rum examples moved to their own repo. There’s absolutely nothing wrong with the original but I did want a simpler structure and most work done on the client. If, like me, you have zero experience with frontend but comfortable with Clojure, you might find present structure easier to follow.
Install and run
git clone email@example.com:vkz/playrum.git cd playrum lein make
Now point your favorite browser to playrum/index.html.
All praise and glory should be directed at tonsky - rum’s creator, author of these wonderful examples. One can only wish more people cared enough to supply their users with extensive examples and adequate documentation.
