It’s that time of year again when the incredulous cower behind their couches as the normally sombre tech industry unleashes its inner sarcasm and goes hunting for the naive. We’ll be keeping an eye out for the best April fool’s japes doing the rounds and collecting them here, but if you’ve noticed any drop us a line and we’ll add them to the list.

Opera facial control

First up is this humdinger from Opera, eulogising the latest development in Opera 10 – facial control. From the press release: “Opera Face Gestures enable anyone with a Webcam to control their browser moving only their face. Based on the same architecture as Opera’s Mouse Gestures, Face Gestures makes surfing the Web as easy as smiling, batting an eye lash or flaring a nostril.”

Topsy-turvy YouTube

If you go down to YouTube today you’re sure for a big surprise. Everything’s upside down. Videos, comments, the lot. It’s a very odd April Fools joke but you’ve got to admire the work that’s gone into it. According to the press release “internal tests have shown that modern computer monitors offer better picture quality when flipped upside-down”. Who are we to argue?

Guardian goes Twitter

There’s no doubt the Guardian has got this web thing down, but could it really become the first newspaper in the world to be published exclusively in Twitter? We especially like the standfirst proclaiming “Experts say any story can be told in 140 characters” – mainly because it’s probably true. Thanks to Ryan Thomas for spotting this.

Introducing CADIE

Anybody heading to the Google homepage today will be stunned to find that Google has perfected artificial intelligence, more so because this AI appears to share much in common with a 13-year-old girl. This one wins the award for the sheer amount of sweaty effort that’s gone into it – a particular highlight is CADIE’s view of how the Google homepage should actually look. To find out more just head to the Google Homepage and click the introducing CADIE link. Thanks to Laurent Cargill for pointing this one out.

-CADIE’s everywhere it seems. The troublesome AI tyke is offering a new autopilot setting for Gmail, a 3D version of Chrome, a Google brain search. She also seems to have pandas on the brain, they’re all over YouTube and Google Maps. We’ll leave it to you to find these.

A funeral with every laptop

Superb stuff from Laptopsdirect, which is offering to pay for your funeral in return for some (tasteful) product placement. Fancy a gravestone etched with a Laptops Direct special offer? Or how about a Laptops Direct jingle played after the funeral music? Well done folks. This is a cracker. Cheers again to Ryan Thomas for the tip.

Google to foist CCTV footage online

Comrades over at The Register are reporting that Google is working together with the Metropolitan Police and London’s Westminster Council to put CCTV footage onto the Internet. Marvellous stuff. We can’t wait to see Privacy International’s complaint about this one.

Dell to buy Microsoft

If you’ve missed the fuss, our own Jon Honeyball got into the April Fool’s lark with this report that Microsoft was eyeing up a Dell deal. It’s not true… honest.

Warner Bros buys Pirate Bay

Well it looks the hostility is finally over. The new logo really is something.
