Crayon Physics (and what about an open-source Crayon-Physics?)

Crayon Physics is a fascinating 2D physics sandbox/game, which came to my attention today when I was reading  Sarinee Achavanuntakul’s blog entry about the sad HotU (Home of the Underdogs) demise and, more than welcomed, revival.  Sarinee mentioned Crayon Physics Deluxe in her blog post, and I checked it out. What I saw in the flash video was jaw-dropping. Crayon Physics  is not just an indie game, but imho a great educational tool in which you really get to experience “what it would be like if your drawings would be magically transformed into real physical objects”. I wonder, is there an open-source counterpart for creative use of physics?

See the video (2.50min, Vimeo):

Update: There is a wonderful open-source alternative, called Numpty Physics, with lots of different levels. Thanks Mike, for pointing to it.


Also, nuclear mentioned a physics engine, called chipmunk. Check it out.

  1. Numpty Physics is one. It is not as well put together as Crayon Physics, but it is one option.

  2. You should also check out armadillo run (demo runs fine under wine)

  3. There’s a very nice free software 2D physics library called chipmunk ( http://code.google.com/p/chipmunk-physics ) which easily supports all the features needed for such a project. I did a simple physics test with that library recently, and it’s got a very simple and easy to use API.

  4. Thank you all for the answers. I think Numpty Physics to be very similar to Crayon Physics. I am not sure how useful it is for kids but it has fun!
