Nothing challenges your brain like a Rubik’s cube puzzle. Matching the colors on each side can be both frustrating and rewarding when you finally do it. Making it all one color would be harder. Say, a brainy pink. Then add some actual brain details and this becomes an extra challenging puzzle.

Not only would this be hard, but you are constantly reminded of your brain, which is struggling. This design comes from Jason Freeny. It may be the grossest puzzle ever. Hopefully the texture isn’t all squishy and wet. Great puzzle for mad scientists.

Your pets should have the same interests you have right? So, if you are a Mac enthusiast, it makes sense that you would want your fish to love Mac too. Now he/she can. This “Macquarium” is made from an old Power Mac G4 Cube. The cube has been specially modified with bonded plexiglas to make it safe for your fish.

This aquarium measures 8.9″ H × 7.7″ W × 7.7″ D. If you have the $149.00 necessary to get this aquarium, go ahead and geek up your fish, changing it’s computing allegiance from neutral to Apple. Maybe you can put a little Steve Jobs figure in there and play Stevejob Squarepants.

The Mintpass Cube MP3 player is for those who love reading meters. The 2 inch cube also sports push button controls, analog displays for volume, battery charge, and frequency, 3.5mm audio out, and Bluetooth. No word on storage capacity or price.

Call us geeks, but we see this MP3 player and we just can’t help wondering what a Borg ship would look like with a battery meter on the side. Of course the Federation would always know when Borg batteries are running low.

Is it a weapon? A PC from the future? The allspark? A cyborg heart from the year 2037? It’s actually BIll Owens’ award-winning NVIDIA ION Cube PC case mod, based on NVIDIA’s ION ITX motherboard. The aluminum case has UV green acrylic sheets, lit up with 4 cathode lights, and then placed on pedestal, where it rotates a full 360°.

The PC also features an x64 SSD by Corsair, 4GB RAM, and a 90-watt pico power supply, along with Windows Vista Premium, and an LG GH22 DVD Writer drive.

Oh boy, another portable media player from the land of China. But this one is a tad different. It’s the Cube H100HD, not to be confused with the cube B52HD. The “HD” isn’t a total scam since it does support High Definition output, but not surprisingly it can’t handle full HD.

The Cube H100HD sports a 5″ WVGA display, support for all the popular audio and video formats and 720p and 1080i video via the out port. They threw in an e-book reader just in case you are mildly literate too. Oh and an integrated FM radio.

The Cube B52HD is a new HD PMP from Cube that comes with a 5 inch (480 x 272pixel) touchscreen display and lets you enjoy 720p videos when you connect it to an HDTV. Sadly, you won’t be getting HD on its 5 inch screen.

The player supports RM, RMVB, MPEG, AVI, FLV video files and MP3, WMA, WAV, APE, FLAC, OGG audio files. Some other features include an FM tuner, and 8GB of storage space. The Cube B52HD HD PMP is currently available in China for $80.

Designer Ji-Hyung Jung is pretty clever as illustrated by this interesting mobile speaker set design. The idea is that you have a cube held together by magnets, that is actually 5 speakers and a sub-woofer.

The whole deal looks pretty sweet once the pieces are out and displayed. And if you want to take them with you, they take up much less room than typical speakers. The volume control is on the top of the sub-woofer. It’s just a concept for the moment, but it’s a great one.

Japan’s National Institute of Information and Communications Technology (NICT for short) has announced the development of an interesting device called the gCubik. The gCubik allows you to visualize objects in three dimensions through its integrated imaging technology.

Essentially you have a box with six screens, that simulates a 3D object inside, that is also interactive via touchscreens. The institute is looking at commercializing the gCubik for use in business, science and of course gaming. Check out a video below.

This remote has us asking a single question. Why? It’s bizarre. Even so, couch potatoes will love it. It’s a cube that flips open to reveal the control buttons. It even has a retro-looking speaker on top.

It has that look about it that says, “I’m an evil genius taking over the world. But right now I need some TV time.” It certainly looks like it’s capable of opening trap doors and remotely flying helicopters, so I guess it has a purpose. You can get yourself this cube controller for just $41.

The Rubik’s cube is more popular then ever. It’s getting a spherical update, it’s also a lamp and it makes a great alarm clock too. So this touchscreen Rubik’s cube makes perfect sense.

Plus, if any toy/puzzle needed a touchscreen, it’s the Rubik’s cube. It’s a natural progression. Obviously the TouchCube works just like the old version, but instead of turning it’s segments, just swipe a finger in a straight line or an ‘L’ shape. There’s even an accelerometer built in so that only the upwards-facing surfaces respond to your touch. How awesome is that?

The Sanko branded Miseal mini projector has a unique cube shape that fits in the palm of your hand, as opposed to typical handheld pico projectors . One interesting feature is that it snaps into a matching docking station for extra juice to supply an additional 2 watts of power for bigger sound.

It’s an LCOS based projector with SVGA, 800×600 resolution. The light source uses white LED to illuminate 25 lumens at 100:1 contrast. It measures nearly 70mm on each side, and weighs only 0.6 pounds. Don’t let the small size fool you as it can display up to a 112-inch diagonal from 16 feet away.

Finally, after all of it’s teasing, LG has officially announced it will launch the LG Arena KM900 flagship at MWC 09 in Barcelona. They also announced some new features, while confirming Wi-Fi and A-GPS capability. The LG Arena will also support 7.2 MBps HSDPA data throughput.

It will come with “Dolby and Divx technologies… and feature audio and video technologies never before seen on a mobile phone”. The real interesting thing is their new 3D S-Class user interface: A cube-based layout that will give you four customizable home screens for direct access to all features on intuitive, touch-based 3D menus.

Sometimes you come across an idea that’s so simple, you wonder why you never thought of it. Or why no one else has until now. This one is a great and simple idea. An ice cube tray that dispenses one ice cube at a time. It’s called the Quicksnap and we’re not the only ones who think it’s a good idea.

It’s a finalist in the Royal College of the Arts design contest, and will be available later this year for single cube action at all your parties. A simple push of the green button and the cube just pops out. So, if you absolutely need to water down those drinks, but want a single cube so as not to water it down too much, you have an easy way to do it.

No, not the candy bar… If you’re one of those people who like to have totally unique and cool objects decorating your home, then why not display the Milky Way galaxy for all to see and be impressed with? This device is also great for those bent on Galaxy wide domination. Imagine being able to hold the galaxy in the palm of your hand while you laugh maniacally at your enemy’s staship movements.

Living World’s Milky Way galaxy 3D model was created using real space data from Eiichiro Kokubo, Assistant Professor at Japan’s National Astronomical Observatory and Osaka University’s Kato Tsunehiko. Holding the galaxy in your hand isn’t cheap though, it will cost you about $770.

Probably not a good idea for those with ADD. The Color Cube basically allows users to create their own specific color combination instead of the usual text based password. As a concept it’s brilliant, but it looks like it takes a bit more time and effort, compared to just typing text in. Also, the slow witted among us will be far too easily distracted. Those people have already forgotten everything they’ve just read up to this point.

The idea is that when you need to verify your identity, just solve the Rubik’s Cube. They say that the color combinations are endless since you can even embed little pictures within each tiny screen if you like. Users also have the option of taking the idea further by making it a time based entry and being forced to solve the cube before time runs out and the colors change.
