How do i get this effect?

Hey, i was just wondering how to get an effect seen on this website…

on the website once the intro is complete… and you click on “XEO Team” you see a bar kind of build itself as it expands from left to right… how do you make that effect???

looks like they just broke the bar up into a bunch of pieces and tweened each one to fade from alpha 0 to white then to black. then set them so they start one right after the other.

i was thinking that… but was hoping that i was wrong…lol… that’ll take like 2 hours…lol
