Can you do a full breakdown of how this was built? Love the page flipping transition!
I noticed one day that the beta channel of Chrome had started to support 3d perspectives, but to my distress their support was buggy and left graphical artifacts. I submitted bug reports and luckily in the latest Chromes it works just as nicely as Safari.
The big thing I got into on this project is CSS animations. They look a bit scary at first but in practice they are not too complicated. I did a mixture of JQuery animation and CSS transitions on this and both have their strengths.
The Node.js code is very simple, it's a small sync script that sits behind nginx. Todos are stored on S3, I used my in-progress S3 library for node.js - can see this here - https://github.com/alexbosworth/Node-S3/blob/master/aws-s3.j...

Both look similar. Any quick commentary on where you plan on taking your s3 lib (features etc..) ?
As for 'bonus features', the only thing I have that most S3 libs don't is support for the S3 feature of uploading very large files in parallel chunks.
