Animation in interfaces is best when used as an education tool: showing where things are moving to, directing attention at important events, &c. Not slowing down obvious processes.
Seems a bit sleazy to me. But I would really like to see some A/B testing between this and a classic form, to know if it really has an influence.
If those fields are required from the start (which they really shouldn't be) they should be visible. The 'verbage' is all wrong.
If you want to simplify your sign-up form, remove fields!
However, if you have a two-part registration, where the first part, for example, requires an email (that needs to be confirmed), you could use something like this to request the next set of registration data while waiting for the confirmation email to be received by the user.
Everytime I click "Registration", I think that I am done, oh wait, more stuff to fill out, jeez all I wanted was [ enter some simple service you must sign up for ].
Before this guy reaches into his Jquery bag-o-tricks, he should first brush up on basic form attributes such as "tabindex" http://www.w3schools.com/tags/ref_standardattributes.asp
