LEGO bricks aren’t just for kids. There’s an entire subculture of Adult Fan of LEGO (AFOL) members who not so secretly build LEGO creations on a regular basis. Did you know that you can also get software, free from LEGO, similar to the software used by LEGO design engineers, to design and plot your very own LEGO creation, brick by brick? How cool is that?

Available for free download, for both Windows and Mac, LEGO Digital Designer allows you to “build your way customizing your own product, or share your models with other LEGO fans in the online gallery,” according to the LEGO website.

Want to build a scale model of your house with LEGOs? Or your car? Or dog? Or spouse? You can do it with LEGO Digital Designer.

Then you upload your design, and can order the blocks necessary to build your design. It’s like being the architect of your own LEGO universe from the comfort of your computer.
