Open the web site.
The Modernista web site is an overlay, a menu that guides you to pages on the web related to the Modernista advertising agency. To learn about Modernista, you are guided to its wikipedia page. To see example’s of Modernista’s work, you guided to flickr. The overlay follows you. If you want to find out Modernista’s contact info, the information is presented in the overlay on top of whatever web site you are on.
I like the Modernista web site because it lets the Web’s strongest web sites do their job. I think there is an irrational compulsion to centralize information on single web pages, even if the information exists else where. Modernista presents a new paradigm.
One problem with the Modernista web site is that the overlay sometimes obscures information on the underlying web page. Fully executing Modernista’s concept of web browsing would require a UI change to the browser.

Update: The wikipedia community didn’t take very kindly to Mondernista’s incorporation of the Modernista wikipedia page. They posted this alert at the top of the wikiepdia page:
The website for this company obscures our logo with their own, and may lead the viewer to believe that Wikipedia serves as their homepage provider. This is not correct. Wikipedia has no affiliation with Modernista and has requested that Modernista cease this use of our website.
Wikipedia is an encyclopaedia written from a neutral point of view and does not endorse nor condemn Modernista, but is opposed to being used as a promotional mechanism in this manner for any third party.
I recommend reading the wiki page’s background discussion. Wikipedia is setting some interesting precedents here — not sure how I feel about it.
