Title should say "animation service" or "animation editor", not "automation service".

Very cool indeed. One minor issue was that the animation seemed to be running even when I switched back to the Draw or Animate tabs, pegging the CPU. Didn't see any reference to Clojure on the site, reference?

    Indeed, how did I miss that. Thanks.

I miss the "made with alien technology" badge on this site. Otherwise awesome work, drcode. Edit: it needs a way to make parts or joints fixed when bending, so I can't turn my train upside down when I rotate a wheel.
- drcode 15y ago
  Agreed- That enhancement is coming in the next point release. (the one about the train wheels :-)

  Roughly how many lines of production Clojure code is this? Is this made only using Clojure?
  - drcode 15y ago
    95% of the code is client-side javascript (i.e. coffeescript) However, the server-side code is pretty complex for an app like this too (read up on creating a large zip file on App Engine some time) but I write very compact code... I'm almost embarrassed to say it's 700 lines of code on the server-side :-) since it feels wrong for so few lines of code to do so much.

      "it feels wrong for so few lines of code to do so much" I love this line.

      The client-side math described sounds pretty interesting. Any chance you'll open-source the CoffeeScript bits? http://www.automatoon.com/documentation/faq.html http://www.automatoon.com/documentation/faq.html says that the player's source is up on GitHub, but that link appears to 404 at the moment.

        sorry- now fixed.

  Awesome work, Dr. Barski! The site doesn't have your name anywhere, but I figured it was you from the drawing style. Yet another piece of awesomeness from you (after Land of Lisp).

Too bad that the video is in Flash.
- drcode 15y ago
  You're right, youtube supports HTML5 video, doesn't it? I'll have to switch over the player so that people don't think the references to flash in the source are from my animation :-)

I have an Apple 27 inch cinema display, and with my browser window more or less full screen the animations seem pretty broken (they were fine after I made my browser window smaller and refreshed) -> http://imgur.com/zdrYk http://imgur.com/zdrYk Also, if it helps: running Safari 5.0.5
