The already massive online archive of photo images is getting larger. Life's Photo Archives are being made available to look at through Google.

The magazine's collection -- totalling more than 10 million images -- includes works by noted photojournalists like Alfred Eisenstaedt, Margaret Bourke-White, Gordon Parks and W. Eugene Smith.

Photos are grouped by decade, ranging from the 1860s to the 1970s, and under these categories: people, places, events, sports and culture. There's also a keyword search function.

This trove of historic photos--- including many that were never published, will expand in the coming months.

If you can't watch an A-list movie, the next best thing is a B-movie. Even better: watch the trailers, so you don't lose a couple of hours that you won't get back.

The B-movie fan's online destination is Trailers from Hell, a site that collects videos the best of the worst, like "The Incredible Petrified World," "It Came from Beneath the Sea," "It! The Terror from Beyond Space" and "Demetrius and the Gladiators." There are more than 200 of them gathered here, with others being added.

The site's "Grindhouse Gurus" section is a guide to commentaries and back stories on the films by directors and film fanatics, including Joe Dante, Jack Hill, and John Landis. Trailers can be watched with or without their commentaries.

If there ever was a mouse that roared, it would be that ubiquitous little gizmo that you're operating as you read this.

The computer mouse is celebrating its 40th birthday this December. On Dec. 9, 1968, there was no Internet as we know it. But on that date, a team of researchers from Stanford University's Stanford Research Institute conducted the first public demonstration of several basic tools that have become part of everyday life, including the mouse, hypertext, e-mail and the cut-and-paste concept.

The original 90-minute video of the San Francisco Convention Center presentation is part of Stanford's collection. It has been divided into 35 short segments and is posted on the Stanford Web site.

For those of you who are wondering what kind of music the next leader of the free world listens to, online radio station Slacker has created a Barack Obama channel among its many music offerings. It features the President-elect's favorite artists, along with music played at his events. Samples of what you'll hear: Bruce Springsteen, Sheryl Crow, Aretha Franklin and Lionel Richie.

The channel was launched during the campaign, with an equal time feature for Republican candidate John McCain. The McCain channel is still online, with music by Dolly Parton, Elvis Presley and Roy Orbison.
