There are only a few days left until Christmas, so anything that saves you time is a good thing. Thankfully, 14-year-old Sanjay Seshan and his 12-year-old brother Arvind built the Holiday Card Plott3r to help in all your Christmas card needs.

Built and powered by LEGO Mindstorms, the plotter can churn out cards decorated with trees, snowflakes and even Santa’s signature. The creation prints the designs using a dot-matrix and even includes a second contraption that slides out an envelope ready for your beautiful, new card.

Better yet, the project files are all online to be used or improved. That is really in the Christmas spirit! Now we just need a machine that licks and applies stamps and drops the cards off at the post office.
