Talk:Poncelet's closure theorem

Some improvements
The previous version implied that that the elliptic curve could either be viewed as a branched cover of C or of D, with branching over the intersection points in either case. I corrected this, and also added a useful link at MathWorld. Hopefully, I didn't make the article too wordy.

I have also written a blog post on this subject http://sbseminar.wordpress.com/2007/07/16/poncelets-porism/ which I think could be useful, but I'll leave it to more experienced Wikipedians to decide whether this is worth linking to.

Is there any proof without algebraic geometry?
