I can only guess that this grip is designed for those whose palms get all sweaty when playing the DSi. And you wouldn’t want to drop your expensive portable, now would you? Well, the Cyber DSi Game Grip will keep it firmly in hands.

It even provides enough space to store another game cartridge on the back with an SD memory card. It’s currently available in Japan, but if you have a severe case of sweaty palm you could always import one.

Snobootz work like a jacket that you wrap around your tires. They have metal cleats that can dig into ice, and the maker claims that they are easier to put on and remove than chains. The doughnut-shaped casing of laminated fabrics is smoother and lighter than chains, so once fitted, the rubber composite design is safe on your tires.

You’ll pay for the design though. They are available for $200 to $250 each. Then again if they keep you from freezing your butt off, they are well worth it.

Sometimes going green can be a real pain. Take this green concept for instance. This iPhone hand grip charger will give you Hulk hands before you even get a full battery. Great for a hand workout, but you’d have to be pretty dedicated to your iPhone to stick with it.

This concept is called “You can work it out” and it was designed by Mac Funamizu, who must have huge beefy clown hands and an always working iPhone. Apple should offer some accessories like this ala Wii Fit. Various exercise gadgets to power up Apple products owned by the obese. It would be green and lean. That’s the slogan right there.

Just how much torque can your finger generate anyway? If you order the Finger Grip Socket Set for $19.99 I guess you’ll find out. I don’t think you’ll be doing anything heavy duty like rebuilding an engine.

It’s a finger-mounted tool that nuts and bolts fit into. You’ll get 10 US sizes (3/16″ to 9/16″) and 10 metric sizes (6mm to 15mm). Even works with your gloves on in cold weather, though they probably should have mounted the tools straight on a glove in the first place. This thing takes working with your hands to a whole new level.

Anyone who has ridden a motorcycle knows that the person on the back can feel uncomfortable when you are in motion because sport bikes typically have no handles for the rear passenger to grab. When riding with your girlfriend its cool for her to wrap her arms around your waist, but other times waist holding isn’t so cool. When your boys want to go for a ride and you don’t trust them with your bike alone, it’s not so cool to have them hugging you.

A guy from Belgium has come up with a solution called the Tankgrip. The designer says the prototype took 4 months to build and ended up looking like a telephone handle on the tank of the bike. In the end he came up with a pair of handles that attach to the tank of a sport bike with a streamlined shape.
