How about a phone that conveniently sits on your wrist? Alexey Chugunnikov has designed the Rollerphone concept and hopes that one day it becomes a reality. It is a wearable cell phone that looks like a wristwatch.

The Rollerphone has a retractable transparent screen at the base, so when you get a call, just pull out the screen. It features a media center, so you can watch videos, chat online, play games, read e-books and more. It will also project the time. One day this will be practical, but for now it is just a concept.

TokyoFlash, those makers of all kinds of wacky and fun watches, have done it again. Now they have created an E-ink display watch to accompany the current e-book craze. Looks pretty sweet. The E Clock can tell the time using normal numbers, or by using patterns of dashes and lines if you like to be mysterious.

It will connect via Bluetooth to your phone, alerting you to calls and texts through vibration or a blinking indicator. It might not look like it, but the band is made from flexible stainless steel. If enough people vote for it, they will make it and offer it up. What do you think?

Man, playing games on the Wii can be hard. You are expected to do stuff like move your arms, hold them up, push buttons… All while holding the Wiimote. Add an exercise game to that, like Wii-Fit and it can be brutal. What, do they think we are superhuman?

Well, Talismoon’s Wiitality accessory can help. What we have here is little more than a neoprene band that holds your Wiimote in place, securing the controller on your arm with Velcro straps. At least they aren’t trying to charge a ton of money for it. The Wiitality will cost you $3 at Amazon.

Check out this wrist-worn PC, if you’re looking for something slightly Sci-Fi and nerdy. It’s the ultimate ultraportable. From Glacier Computer, the Ridgeline W200 is a wearable version of the company’s Ridgeline, which can usually be found in your vehicle. The case is rugged, light weight magnesium alloy and it weighs in at 10.2 ounces with a 3.5-inch color display, touch screen, backlit keypad, and a swappable battery pack.

You’ll also get support for Wi-Fi, Bluetooth, and GPS modules. It comes with Windows CE or Linux, sporting features like tilt and silent reckoning for putting the device in standby.

Meet the dorkiest looking wrist accessory ever. You might think this is a cool cyberpunk bracelet thing. Actually, it’s the ultimate way to charge your batteries and look like a loser at the same time. If you don’t believe me, then by all means, check out the product site. There you can find pictures of people wearing and using this device.

It’s sad that it looks like such a train-wreck, because it’s a convenient way to charge up all your gadgets on the go. It uses a rechargeable li-on battery and comes with 8 different types of power connectors that will work with major brand mobile phones, the PSP and Nintendo DS. To recharge the portable battery, it takes about 5 hours. When used as a direct power source, it’ll give you 3 hours of talk time or 8 hours on your MP3 player.

In these troubled times, you don’t want a super expensive phone with all the bells and whistles… Okay, you do, but for a moment let’s just pretend. The Disposable Pre-Paid Phone concept is one of the most basic handsets you could hope to find. The idea is that it would be affordable enough for anyone to purchase for use in an emergency situation.

Which makes sense. You would want a portable phone you can wear it around your wrist, for Dick Tracy type emergencies. How billing would work is anybody’s guess. But it looks great in Wii-white. No alphanumeric keypad here, which is lame. Sometimes in an emergency, sending text messages is a good idea.

Flexible OLED displays are becoming more commonplace everyday. They just need to make it into some of the devices we can buy. However long it may take, when that day arrives, Universal Display Corporation thinks something like the gadget above will be a part of it.

It’s a wearable, flexible, 4-inch prototype screen that CES attendees will be able to drool over, maybe even wipe clean and try on. Just don’t expect to wear it comfortably. It won’t be in stores anytime soon either. This one was developed with military applications in mind, but bendy consumer devices are on the way at some point. Give it a few years and we will start seeing them in passports, clothing, packaging etc.

We knew that eventually a watch phone would show up that packs in all of the features we want.Turns out that it’s LG who has accomplished this with their LG-GD910 model. The phone sports a touchscreen LCD, 3G data, and a built-in camera for videoconferencing and looking cool.

Of course using that 1.43-inch screen, it might be tough to browse the internet, but it’s all about looking cool, not what you can actually accomplish. You can’t get one now and we don’t have a price yet, but LG should be showing it off at CES next month. They plan a release in Japan and Europe, but that’s all we know.

The Torus concept watch from Nicolas Meiresonne won’t give you the exact time. But it will look pretty in a Sci-Fi kind of way. This timepiece offers the wearer only a perception of time, by cycling through a variety of pretty colors.

For instance, you’ll get blue and green in the morning, while yellow and orange mean noon with red and purple depicting both evening and night. The bracelet’s surface has touchscreen capability, allowing you to set the timer simply by tapping on the corresponding segments. Pretty cool, but pretty useless if you need to know appropriate times.

John Maushammer enjoyed some minor fame in geek circles with his Pong wristwatch, but he craved more. So he delivered unto mankind a new great thing. The DIY Asteroids Watch outdoes it’s predecessor.

It even features a tilt sensor so the wearer can control the action by just tilting their wrist and going pew pew pew. Frankly, we could go on about it all day, but the bottom line is that the man is a DIY game watch god. Check out a video below.

Tokyoflash, those wild and crazy watch makers just never take a breather. Which is great for us, because if it wasn’t for Tokyoflash, watches would be boring. They’re back, having never left, with their latest wristwatch known as the Ni.

This design is at once stylish and minimal. The Ni is made entirely from stainless steel and features a polished finish, with horizontal grooves on the face and strap that give it a great look. The time progresses in one direction. Touch the upper button for an animation before the time is displayed. Each LED on the bottom line indicates two hours, the line above indicates a single hour, a combination presenting the current hour. Groups of 10 minutes are presented on the center row and single minutes on the upper two lines.

This watch is great for Boom-Box enthusiasts whose arms are too frail to carry around the real thing. Flüd’s Boombox watch looks like an actual tiny version of the Boom-Boxes of yesterday. The watch even features an old school 7-segment red LED display that looks authentic to the period. Unfortunately those small speakers don’t pump out any tunes. The Boombox watch is available in shiny silvertone or gunmetal grey for $90. Unlike the real thing, half of it’s weight isn’t due to D cell batteries.

This Steampunk creation is pretty cool. There’s just so much of it that you have no wrist left and it looks like it would give you carpal tunnel syndrome and make one arm look like a weight lifter while the other is thin and geek-like. Sure is a lot of leather work around the metal flip-open watch.

It does have a certain authentic antique look about it. And I can’t tell you what the whole finger strap is about because my translation skills aren’t up to it. My guess is that you wear this while riding your bicycle and when you see a pretty lady, you activate a bell with your finger that dings, letting the Victorian hottie know that you noticed. Then one day they’ll invent the bicycle bell and your wrist can be free.

If there’s one thing you can say about the Wii, it’s that it is and always has been white. Back in the days when it was first called the “revolution” it seemed like we would be getting an assortment of colors, but alas, just plain old Wii white. That’s why it’s kind of shocking to see these.

While this may not be a lime or blood red Wii console, at least Nintendo is taking a baby step in the right direction with these pastel-colored Wiimote straps for Japan. You can get the whole pack for $10 or individually for afew bucks. No word if they’ll be coming our way soon.

If you happen to see a guy or gal wearing a wrist knife like this and approaching you on a darkly lit street, you’re gonna wanna run like hell. I think it’s safe to say that this thing could probably gut you real fast.

What could be scarier then than this? The price. At under $40, any psycho stalker, or goth D & D misfit can afford one and take to the street. See, this kind of thing here is why we need Batman to be real. It’s just crazy. You can also get one in dragon or skull form.
