People over here have such a hard-on for efficiency and speed. I'll give it to you, transitions are on the long side - I wouldn't mind the transitions taking half the time they do now, or the image descriptions taking less time to darken. However, if the idea was just to be a simple image gallery they'd just give us a .zip file. It's obviously meant to be a laid back and slow experience. IMHO here it's definitely too slow, but people over here seem to hate everything that's not a blank site with 0 animations.
I work back-end dev, I used to think everything flashy on the frontend was a waste of time. I then worked in a web agency, I've seen the thought process - usually, with _good_ designers and UX specialists, the overall experience is tailored to whatever feel they want the site to have. I worked on a virtual expo site with a museum once, it was _meant_ to be contemplative and slow. You guys would have immediately hated it, while if you took two seconds of your life to just let yourself be immersed, the whole thing was a great experience.
People over here also love to rave how this is anti-user, but you people are misunderstanding the average user. Power users like you are the minority. Most people don't mind the animations, and a lot of them actually enjoy it.
