This environmentally friendly calculator is great for your kids! All you have to do is fill the fuel cells with plain water and you’re good to go. It operates just like a normal calculator, but it’ll teach the kids that there are alternative ways to science. It doesn’t get any more eco friendly and educational than this Hydro Power Calculator! :)

Cleaning your computer can be quite nerve wrecking without the proper tools, so I have a recommendation for you: the USB Powered Mini Vacuum Cleaner! This tiny vacuum has a conventional brush nozzle and a special rubber nozzle for hard to get areas. Just plug in your USB port and start cleaning right away!

There’s no excuse for that dusty keyboard now, is there?

I believe we’ve all taken out some heat in our days on our computer or at least keyboard. It can be incredibly frustrating to lose a race in Need for Speed, or a match in Football Manager or get whooped in WOW. So you feel like destroying some stuff and since it’s not healthy to take it out on friends or family, it’s advisable to let out your nerves on inanimate objects.

But since it’s not very economical to replace the keyboard every now and then (depending on your moodiness), I’d advise you to get yourself one of these here Virtually Indestructible Silicone Keyboards. It’s a silicon-based flexible computer keyboard and you can roll it and torture it as you please.

You’re overheating, your laptop is overheating and everything is just too freakin’ hot. No worries! There’s a gadget for that. The USB Cooling Chill Pad, with 3 reliable fans, a sleek, compact and light weight design will cool your hot laptop in a jiffy. It also has a low noise level, so you won’t feel like you’re working in an industrial plant. And, if you’re a man, it’ll keep the family jewels safe, taking into account the fact that doctor have said that it’s not the safe to hold the laptop in your lap.

I have set up all kinds of alerts to tell me when I have a new message. Or email. Or a new mention on Twitter. Or if I get a new like on Facebook. They all ring, pop out and sing, sometimes simultaneously. It can drive a person mad at one point.

Not any more! I like this little thingy called the USB Mailbox New Message Indicator. What it does is inform you every time you get a new message (be it email, Facebook message, tweet or anything else). It’s made to support gmail, yahoo, outlook, outlook express, Windows Live, Live Mail, POP3, Facebook and Twitter. It has a sound illumination reminder and the flag rises with every new message. So cute! Just plug it in your USB driver.

I dream of the day when we won’t need to use any paper at all, not because I don’t think it’s kind of romantic to write on actual paper, but because it’s mostly a waster, especially ever since computers have taken over our lives. One gadget I want to buy is the Scratch-n-Scroll Mousepad. It just brings me closer to my dream.

It has a smooth scrolling surface, which you can write on and erase with any optical/ball-based computer mouse. So you’ll need no more notepads or post-its. Long live the few forests we have left!

Friday is Top 10 day. So if you’re working late (like I am) and spend most of the day in your office (which we all do), you need to improve your work environment so that it gives you all the comfort and relaxation you need in order to be efficient and creative. Here’s a fine selection of gizmos, gadgets and other things that can make our office a place we love to be in.

1. Decorative Sticky Tape – not your usual cute, cuddly, colorful decorative scotch tape, but certainly pretty and quite fancy I might add. It’ll add a personal touch to your envelopes, gifts and other wrap needing stuff.

3. Wave of Light Dolphin - there’s nothing like having a soothing, relaxing object on your desk so that you can turn your eyes to it whenever they feel sore or when you feel like your head is about to pop. This little lamp combines lights, sound and movement and they say it can kind of hypnotize you. It even moves like the ocean’s waves. Do you love it or do you love it?

4. Suck UK Door stop - I hate people who slam the door open or closed when they come into or leave a room. The sound is annoying and it can scare you if you’re really focused on something. So I have a solution for you! These door stoppers will not only stop doors, but maybe also prevent anyone from entering, since they are pretty cool and exclamatory.

5. Ceramic Swear Bank - we all hate meetings and most of us come out swearing. So this got me thinking and I came up with an idea to get you rich: you can make you office a swear are and cash in for every curse word that your colleagues utter.

6. Grass Charging Station – this will add a very nice touch to your desk and it’ll help you keep all your gadgets charged and ready to go at any time. Don’t worry, it works with any small device with a charging cable and it has a special compartment for hiding all the wiring.

7. Explosion Notepads – if you’re trying to make a statement and your coworkers just won’t get it, because punctuation is not particularly relevant to them, try these instead. If it still doesn’t work, try shouting. :))

8. Another possibly annoying thing about your colleagues (and maybe even about your boss) is that they always ask to borrow a pen and they always forget to return it. It’s like an unwritten rule of the office. The worst part is that they usually take away your favorite pen. Although we don’t use them much these days, we can’t say we still don’t get a bit attached to our office stuff. In my case, it’s a thing I have inherited from grad school. Well, no worries, use a Bank Pen and you’re safe. They’ll never steal your favorite pen again.

9. Monkey Picked Tea – looking for a relaxing and energizing drink? How about a cup of tea made out of leaves picked directly by the gentle hands of… monkeys? Yes, you read correctly. Here’s a little something about the product: “Legend has it that Buddhist monks trained monkeys to harvest the leaves from the top of wild tea trees.” I wonder why I haven’t seen this on Discovery yet. How Zen is that? :)

10. Whatever Wall Clock - not in the mood for deadlines? Neither is this clock. It’ll melt away hours and make you forget all about your long to do list. Who needs chores on a Friday afternoon? Have a great weekend!

My neck has been killing me lately and as much as I love my laptop, I sometimes wish I had a desktop, so I don’t get a hump until I’m 30. The cool Fellowes Office Suites Laptop Riser Plus has a lot of things I like: you can adjust it to eye level (so you don’t get back pain, like me), you can even rotate it to 360 degrees for easy viewing, the very useful cooling vent and an In-line copyholder.

Awesome? Yes! Worth every penny? Yes again!

Mousepads. They come in all shapes and sizes, colors and textures. But how about a Fierce Teflon & Steel Mouse Surface? Since multiuse is one of the best thing we like about gadgets, why not make a mousepad you can cook burgers on? When you’re done with frying them, you can serve them while they’re hot, right next to your mouse. Cool? Definitely! And I love the name!

I’m a big fan of black laptops and notebooks, but I tend to get tired of the same look and the same keyboard. Looking at them every single day does that. I’ve been thinking of buying one of those stickers to cover up my laptop, but I’ve recently come across another improvement that you might like (especially if you’re a Mac owner): the MacBook Keyboard Decor Decal Sticker.

This particular model is designed to make your keyboard look like a rainbow and it couldn’t be prettier! One of these would really lighten up my days!
