There is a whole realm of hacking that isn't necessarily to do with computers.  Hacking is the art of learning how things work and implementing them in new and interesting ways.  I've found a website that specializes in this form of hacking.  Kipkay Videos features some very interesting articles on how to modify everyday items in order to make them work for you in ways you may not have thought of before.

You can find videos on everything from making your own illumninated keyboard to improving your gas mileage, or even using your phone line to provide power for a lamp during a power outage!  Pretty much anyone can take advantage of this form of information.  Hacking of this nature can be used by anyone, anywhere without the intense technical knowledge needed by computer hackers. 

There are lots and lots of places to find information like this.  One of my favorites is Instructables.com.  On Instructables, you'll find so many projects your head will swim with ideas.  Not only does it provide a great number of things for you to try, but it also can ignite personal inventiveness and inspire you to create your own projects.  This form of hacking is very rewarding and very readily available to anyone.  You can hack anything, anytime, anywhere as long as you've got a vision of doing so.  If you can think of a cool hack, do it and tell us about it.  Post it some information about it so we can do it too!
