Build a Lego Machine to Print Holiday Cards for You It might not save you time, but it'll be muc

Sending out cards to all your family members can be the worst part of the holidays. If you have an especially large family, it can take days to fill out, envelope, and mail every card. Fortunately, there's a better way.

If you're up for playing with some Legos, you can break out your Mindstorms kit and build a little robot to make your cards for you. Take a look:

This robot is called the Plott3r, and can create pretty much any image you want. In this case, it's being used to draw festive images on cards. The machine can also spit out an envelope for you to put the cards in, making your job that much easier.

Of course, you still have to build the robot, so it might not actually save you any time. But at least this way is much more fun.
