All you do is get a kit, imprint your lover’s (or even your own) fingers, send it off, and get a custom fingerprint ring in your choice of metals. The message the maker of these trinkets wants to send is that “your lover touching you, holding your finger, always with you,” but all I’m hearing is “make sure it’s not her sister…make sure it’s not her sister!” [Etsy via Make]

It’s true. We (being astronomers and people far smarter than I) really don’t know. But we do know where this mysterious event took place: One million kilometers away, in Saturn’s F ring.

The pic was snapped by a school bus sized gadget we call Cassini. It’s been orbiting Saturn since 2004, and the wealth of data, photos and knowledge beamed back to us in that timeframe is nothing short of amazing.

But this latest snapshot is an enigma. Something punched through the F ring, violently spewing a plume of dust, ice and rock out into the nothingness—but what?

Even more mysterious is the bright spot left in the object’s wake. Icy crystals laid bare for the Sun’s rays? A new material? A cosmic mooning from some alien prankster? Possibly, but whatever it is, it’s yet another reminder of how violent and unexpected space can be.

Isn’t that right, Jupiter? [Bad Astronomy]

In the tradition of the Atari ring comes this gold Optimus Prime ring from deviantartist =Dans-Magic.

It’s the perfect gift for that special someone. That same special someone who’s willing to wait hours and hours in line with you at a premiere so you can go into the theatre to watch Transformers: Revenge of the Fallen and ogle Megan Fox half-naked on a motorcycle. [Geekologie]

Brando’s new button spy camera is one step closer to international super spy. You wave an ordinary looking gold ring near the device to take photos and video.

That’s right, friends. No more pesky fiddling with your buttons when you’ve infiltrated deep inside the Russian Parliament.

Priced at $US96, we’re not exactly sure how the ring communicates with the camera. The technology could be based upon RFID, magnetism or simple metal detection. But we do know that 1200×1600 images and 608×488 video (at 15fps) should get the job done well enough, though you’ll still need a decent explanation as to why you’ve been caught in the Russian Parliament’s lady’s locker room, wearing a wedding ring no less!

You have to inject the perfumes into the ring with a hypodermic needle which is supposed to invoke the “clinical process” of getting ready for a date. The scent is emitted you squeeze the side, causing the tiny piezo tubes to contract.

Oh, the feather’s just for decoration—I’m not sure it’ll help you get laid, either.[NYU ITP]

Oh. Oh that’s what it is. A cybernetic pop-up penis. [SheCoolHeCool via Fashionably Geek]

According to researcher Saori Noda—who works for Denso Corporation, a big automotive electronics supplier in Japan—they are “working to make it smaller and less noticeable.” This doesn’t explain why they decided to make it the shape of a big honkin’ cat face, but sounds good enough to us.

The device can detect tiny electrical currents going around the body. To work, it generates a current that goes into the index finger. When you press your finger and thumb together, the ring detects a closed circuit and interprets it as a signal, sending a device a control order wirelessly.

According to Noda, this could be used to control any kind of device without touching it, including phones, music players, cars, and whatever you can imagine. [Pink Tentacle]
