Just as booze is the miracle juice, I think LEGO is the miracle brick. You can do all sorts of stuff with it, like rebuild the entire Batcave or put awesome LEGO starships together. The sky's the limit, really, as long as you don't hold anything back and happen to have an ample supply of LEGO bricks at your disposal.
This time around, it's not just stuff that you can gawk at (although the Totoro Bus is an exception.) There's a coffee mug, an actual Guitar Hero LEGO guitar (I know, pretty sweet), and a fully-functional LEGO PC! I don't know how they built it or why, really, because who the heck needs a computer made out of LEGO? All I know is it's awesome and the Internet is a funner place because of people who come up with quirky stuff like this.
There's even a pair of glasses made entirely out of LEGO in the mix, although its maker hasn't figured out a way to fit in lenses yet, but that's okay. It's easy to convert into 3D glasses, anyway.
Check out the gallery for some awesome LEGO creations that you can use, boot up, and abuse. Enjoy!
