fml the timing on those animations is perfect. where would one learn to do that?
play around with after effects for the weekend, you'll get that hang of it sooner than you think!
But ..those transforms and manipulations. How is this possible in After Effects?
I'm not sure but I know it is, I've been using AE a lot this month to create some animations (that are nearly impossible with CSS/JS alone) for a new website that I'm working on. Looking at them, they are definitely possible through AE, it'll just take you some time to learn for sure ;)
Seriously... they are all so beautiful and smooth
Learning animation isn't hard. Timing takes years to nail down well. Read up on timing theory by Richard Williams.
Imagine this as a webfont :-), 5 years maybe?
