Working with a mouse can rapidly wear on you, especially when you get acquainted with the carpal tunnel syndrome. Time to liven up that crowded desk of yours with a special rodent – the Disco Ball Mouse.

I reckon this is a must-have peripheral for the ladies. Lights start to flash as you scroll across spreadsheets, documents or spammy e-mails. Your office or home desk could be easily transformed into a cool light show that grooves to your favorite beats.

The disco ball mouse has been designed to resemble a real disco ball cut into half and is made in bright funky pink. Hidden within the ball mouse are a number of red, blue and yellow lights which flash as you work your way through tons of documents. In addition, you also get a funky mouse mat that looks like a real dance floor.

How exactly do I transform my desk into a dance floor? Place your mouse on the mat provided then plug the mouse into one of your free USB ports on your computer. Once plugged in, the mouse will work like any other and it will also flash like crazy as you move it and scroll or listen to some music.

So what are you waiting for? Get your hands on a disco ball mouse and start the party for only $19.99.

Trackball mice are back with a vengeance! Meaner and… smaller than ever, infiltrating you laptops all around the world. It’s the Genius guys again, and this time they declare war on big, power-hungry rodents.

In order to destroy the competition, Genius designed an optical mini trackball solution, the Traveler 350, which delivers superb working performance and comes with an adjustable jig. This new feature can be used with either hand, reducing any wrist injuries. It also comes with built in hotkeys to increase your working efficiency as well as media center control.

The hotkeys are especially designed for Windows Vista users: you got the Flip 3D application switcher and instant access to Media Center. In addition to the ergonomic stuff, there’s a retractable cable for easy storage, so it’s not wireless unfortunately, and it pops into a USB2.0 connector, which means its pretty responsive even in games. It’s suitable both for right-handed people as well as for lefties.

If you ask me about it I’d say it’s pretty small. I mean it’s no larger than a key-chain holder. Genius sure knows what infiltration is all about with toys like these. If this doesn’t impress you, check out its price: $46.51. So small, yet it costs just like a normal one.

Most of us are enjoying the sleek look and feel of a traditional mouse. You got everything right where you need it, or at least were you got used to finding it. But Microsoft has other plans for their optical mice.

It’s not only an optical mouse, but it has a trackball too, supposedly combining optical precision with ease of use and ergonomic comfort. Microsoft tell us we should expect only top performance, with thumb-controlled accuracy, customizable buttons, an easy-to-use scroll wheel, plus some Internet buttons.

All good, but why optical and not something laser-powered? MS assures us that this mouse integrates the fastest, most accurate optical technology on the market, which delivers excellent tracking speed. It’s PC and Mac-compatible and we see some kind of reconciliation act on MS’ behalf.

The scroll wheel is already standard but I’m really curious about this trackball. MS claims that we are to experience accurate, finger-operated control and effortless navigation when using the ball. Well now, if you operate the cursor with your thumb, why not use some powerball to train a bit? And looks like it’s only for right-handed people.

You can use either a round PS/2 port or a rectangular Universal Serial Bus (USB) port for plug-and-play convenience. Strange enough, most people say the PS/2 is faster than the USB port and that’s why the mouse makers still stick with it.

Who’s up for some mousy experiment? $44.95 if you’d please.

Sometimes I wish I could operate my computer only with my mind, or at least with the mouse. No more multimedia keyboard for me! Well, mine’s wireless, but I could use some sort of keyboard mouse for a change. While Belkin’s hybrid controlling device for gamers could be an interesting idea, the closest thing to all-in-one mouse seems to be the 11 button multimedia mouse.

This is some sort of Swiss army mouse that gives you plenty of advantages over that redundant pesky keyboard. Why put all those multimedia buttons on the keyboard when you can squeeze them all on a nifty mouse? Here are the buttons you’ll find on this feature-packed rodent:

- Play and Pause
- Internet
- Speed Switch (800 / 1200 / 1600 / 2000 dpi)
- Page Forward / Page Backward
- Volume Up
- Volume Down
- Double Click
- LED Indication (Yellow for 800 / Blue for 1200 / Green for 1600 / Red 2000 dpi)
- Left Button
- Right Button

Now you can master most multi-media functions with your mouse solely. I’m not too sure about the ergonomics, but hey, it’s USB 2.0/1.1 compatible, it’s got an optical sensor and knows how to deal with Windows 2000/XP and Vista in an elegant manner. And all this for just $14.99. You can find it here.

If that compact mouse from MoGo seemed strange to you, check out the Slim USB Mouse! It’s the USB mouse with only one button and a scroll wheel. It clearly is designed for portability, but it also does away with almost everything you might expect from your everyday mouse, incorporating the bare minimum in terms of ergonomics.

Suddenly, your fat and happy digital rodent turned into a skeleton – minimalistic device. The specs seem decent enough, though. It’s black and half-transparent red, equipped with a 800dpi optical sensor. It has one top button with a patented front/rear operation, so you actually get an interesting 2-in-1 button and a scroll wheel at the side. But how small can it be? Like 3.23 x 0.94 x 0.71 inches and 3.17 oz. Born to travel, indeed. Get that bony mouse for only $11.32. Do it for your faithful doggy, at least.
