It's that time of year again. The time of year when people all over the country spend tons of cash and devote hour after hour after hour to put together a holiday light and music show that could probably be viewed by the astronauts on the International Space Station.

The Johnson Family of San Antonio, Texas, are those kind of people. You might remember them from season two of ABC's "The Great Christmas Light Fight."

Matt Johnson explains:

Started in 2013, our show is not your traditional light show! There are no inflatables, characters, blow molds, or other "traditional" elements. Even the music is not traditional Christmas music; it is a custom sound track composed of Dubstep, EDM, hip hop, movie clips and even our children! The result is an exciting show that feels like a dance party! Even the lights are not traditional, we use Pixels which are similar to what you would see in a stadium Jumbotron. Each pixel can be controlled individually and set to any color and intensity. This means many more effects than what can be done with Christmas lights! The show embodies the spirit of DIY and cutting edge technology with all custom built elements, kit based controllers, and both custom and open source software.

Got all that? Don't worry if you didn't, because Matt will show you how to do your own mega-display. Click here for the how-to.

The Johnson Family is also raising money to build wells for clean water in African villages with the Clean Water Challenge. Find out more, or make a donation here.
