XP Bar

[1nfinitum]

This is a request, unless of course somebody knows of a mod that already exists that does what I'm looking for. Basically an XP bar. To replace my old one, with the notches and stuff (preferably incorporating the bar system of the original XP bar) I found a video that uses the one I like, however it is quite old. If anyone knows what mod this is, or anything close to what I'm looking for please tell me... Otherwise get to work! >:P

EDIT:

Whoops. Here's the video:
