Google Labs, that breeding ground for the wacky, sublime, and sometimes useful experiments that Mountain View's scooter-loving employees are so fond of, is getting ready to "wind down." The software giant announced today that the experimental forum for testing out potential features is being sidelined, in order for the company to focus on bigger picture ideas. Some of the more useful experimentation for properties like Calendar and Gmail will stick around, as will the Labs experiments that eventually made their way into the Android market. Google has promised to keep us all in the loop during the transition, so perhaps we can pick up a few secondhand test tubes for our own collections.
