From my understanding it's a direct link to minecraft creative mode, most likely without any other text on the page.
EDIT: I want to try this out but I can't get chrome to start up with apps enabled.
What I should be doing is putting this into the target box, right?
"C:\Documents and Settings\User Name\Local Settings\Application Data\Google\Chrome\Application\chrome.exe" --enable-apps
EDIT: Got it working. All the app does is take you to http://minecraft.net/play.jsp. The difference is that it makes it an app tab that is harder to accidentally close and has some other priorities over other tabs.
