@seblavoie Your script works only in english. Have a look at this https://gist.github.com/4160147 Cheers :F

Thank you for your tutorial. Somehow when I execute your script, I got an error message, saying that
line 11 is undefined. Thus, I comments out and it works. // currentComp.openInViewer();
Could you help me understand why it happens?

@shh1cd Sorry it took me a lot of time to notice your question, but currentComp.openInViewer(); only work in CS6+.

Thanks for the explanation of how to create shape layers. I hit the brick wall in the documentation and finally found this tute.

Just a note: you could add the stroke and fill attributes to the createEllipse function to tidy it up a bit and make it more re-useable.
