1. Self-Guided Bullet

This formidable projectile is more like a micro-mini missile than a bullet. Developed by defense lab Sandia, its self-guidance system lets the four-inch projectile nail a target a mile away.

It doesn’t spin like conventional bullets, because it has fins that make it fly just like a tiny smart bomb. The weirdest part? The farther away its target is, the more accurate it gets.

Still under development, it’s not available yet, but when it is, just hope you’re not on the wrong end of such a guided missile.

It’s been an unusual week in the tech world, yielding gadgetry and innovations that are surprising and altogether unexpected. Here are the top 10 we found.

The theme we kept running into in our journey into the techosphere this week was wish fulfillment. We’ve been wishing for a self-refrigerating can for decades; we’ve hoped for a waterproof iPhone, smoother slow-motion on football games, and a high-quality video editing system we could use on a tablet.

Beyond those items, we found lots more. And then, after quenching our thirst for certain conveniences and innovations, we figured it wouldn’t hurt to toss in a couple of superlatives, giving you a gigantic contrast between the tiniest self-propelled vehicle we’ve ever seen and the most gigantic diesel engine we’ve ever imagined. It’s a study of contrasts, indeed.

Come along with us on a journey from the sublime to the ridiculous, as we lay down a gallery of Top 10 Tech This Week.

Here’s last week’s Top 10 Tech.

Nokia will be shutting down its Ovi Music Unlimited (also known as Comes With Music) service in 27 countries due to lack of interest, Reuters reports. The service will stay live only in select markets including Brazil, China, India, Indonesia, Turkey and South Africa.

The service provided customers with unlimited, free music downloads included in the price of the phone, and was backed up by Vivendi’s Universal Music, EMI, Warner Music Group and Sony. However, the music was protected with DRM (Digital Rights Management) software and tied to the device, which drove off many users. “The markets clearly want a DRM-free music service,” said a spokesman for Nokia.

Ovi Music Unlimited users will still have access to their old tracks after the service is shut down, but they won’t be able to buy new tracks. Nokia will continue to run its music store in 38 countries, where users can purchase DRM-free music tracks.
