It's also all javascript now, no more php. I'll push the code later, but in the meantime you can view source on the page.

What they do is obvious, why they're necessary is not.

I went to view my skin and bits of it didn't render.

If I look at the skin bitmap in the bottom left, it looks like this:

However if I fetch my actual skin from the Mojang server, it has the rest of the outer layer:

Can you add skin rotate function? (On mouse drag?)

I found one, http://minecraftskins.herokuapp.com/
Source Code: https://github.com/a9io/cors-minecraftskins

Change lines 197 and 1008 in index.html if you want to use their hosted site.It worked fine for me.
197: img.src = 'http://minecraftskins.herokuapp.com/skin/earthiverse.png';
1008: img.src = 'http://minecraftskins.herokuapp.com/skin/' + document.getElementById('username').value + '.png';

How to use this?

Supporting HD skins (for example 256x128) would be very cool! Maybe it's enough to change only skin2d.js

This library is wonderful. However it is licensed under GPL. It isn't convenient for others to use this library but licensed under other license. I suggest to re-license this project to LGPL or MIT. (MIT is most popular for many JavaScript projects.)

I should have the code kicking around somewhere that generates static 3D skins in pure JS.

I could update it to work with 1.8 skins and add them in. If I get bored one weekend over the summer, I'll do this. :)

Change the thread on bukkit to refer to github after I move over all of the projects.

Remove the comments that contain my name, maybe make a contributions file or have no contributions listed (they will be listed on this github, non?)

If it can be allowed, I would pull request with that function. By the way, could you please provide a website from which viewer can load cape.
