The application is aptly called TiltShift. It costs $2, and while it doesn't use traditional tilt-shift lenses, the software adds some blur filters to create the illusion. The user selects the part of the image to be in focus/tiny, and the software feathers the surrounding area appropriately.

We're not sure that TiltShift's simple, even if effective filters are worth $2 to us, but the free clone app that's surely just days away will be a fantastic way to kill 10 minutes. [TiltShift via Wired]

It works by recording a soundbite, uploading it to Google's servers, which will crunch the data and return an answer "within seconds on a fast wireless network". Saul compared the function to that offered on Yahoo's, and found Google's to be more accurate, but still return junk results sometimes. AT&T and Microsoft also have handset voice recognition beyond simple dialing that many other phones offer. The app will be free and might be available to download as soon as Friday. [NYT]

Mercedes-Benz C63 AMG App: Surely fast-tracked by AMG fan Steve Jobs (head of the queue!), for the rest of us, this is a reminder of what we will not soon experience first-handphotos and videos of a sleek, six-figure Benz, and sound clips of it peeling out.

Sonic Boom: Those folks behind the Sonic Lighter (and the voice-shifter above also, coincidentally) just can't stop innovatingSonic Boom gives you a virtual firecracker onto which you can map a photo, adjust the size of the charge and length of fuse and spin around before making it go boom in a different-every-time explosion. $1.

Mustache: I haven't shaved in days, but what's on my upper lip is barely perceptible as anything beyond 7th-grade fuzz. As the developer of Mustache states: Mustaches are a symbol of power and virility, who wouldn't want to grow one! Sadly, not everyone one can. Hand over a buck, hold a picture of a mustache in front of your face. If you're not bold enough for this tattoo.
