As a marketer, I can't imagine that there is a ton of long term value here. But it seems like that's baked in because it's a one time payment, and the prices are very reasonable.
There's also just enough customization options that I am already thinking of clever ways I could try to stand out.
As others have mentioned, though, the big benefit of the first million-dollar homepage was the SEO value - along with the fact that for a few hundred bucks, you could have a bold ad that caught someone's eye amidst the chaos (FREE HOSTING comes to mind). The novelty of the project sold it to mass-market PR, which then sold it to the public, who then shared it with their friends.
As pretty as this project is, I think there's a lot less novelty here.
The novelty here is more WebGL, as well as the "Hey, someone's doing this again." WebGL implementation will attract the attention of a select few people; the "here we go again" will likely also capture a few clicks, but none like the first time around. The story just isn't as good for mass-media to run with.
So while my right brain starts to go through 'how can I work with this?', my left brain chimes in with 'I can get a whole lot more ROI from $2k worth of Facebook ads this time around.'
Still a cool idea and very pretty to look at, though. If you get in early (so you can stand out), it might be a good buy.

This is like marketing catnip.
