The LEGO Death Star was constructed from 500,000 LEGO bricks and captures the scene in the 1977 "Star Wars Episode IV: A New Hope" in which Luke Skywalker bravely guides his X-wing fighter through heavy combat to destroy the deadly mega-weapon. Hopefully LEGO has hidden the Death Star plans out of reach from the Rebellion this time!

Using a preexisting pattern for a printer, he reworked it with new hardware and software enhancements to print out letters in braille, calling it the Braigo. The Braigo uses a controller that scans the alphabet. You choose a letter and it prints it out using a thumb tack as a printer head onto on a roll of calculator paper.
The first prototype isn't fast, but it's a concept that works, and works well. Banerjee is working on enhancements that will allow it to print full pages of text.
You can view more information and enhancement updates at the Braigo Facebook page here.
Finch also created a LEGO Hogwarts replica in 2012, totaling over 400,000 bricks. Pretty awesome for die hard fans of both films!
