DIY of course stands for Do It Yourself.
When I was a kid, I was always fascinated by MacGyver, a character who would create all sorts of cool stuff from nearby objects. It was somewhat improbable, but definitely fun to watch.
Many things now can be taught through video instruction, especially with the dawn of the YouTube age. I've always enjoyed checking out sites like ehow.com for text based tutorials, but there are sites that are starting to spring up that show you how to do things via video.
For example, check out the Web site below for all sorts of videos, from things as normal as "how to sew" to things as bizarre as "how to trap eels".
Thanks to Dave M for the heads up!
