The EFF is describing it as "a break for your brain." An anonymous reader writes: Humble Bundle has announced a special "pay what you want" sale for four ebooks about LEGO from No Starch Press, with proceeds going to the Electronic Frontier Foundation, or to the charity of your choice. The ebooks include Beautiful LEGO (a compendium of creations by dozens of artists) and Medieval LEGO, which describes and recreates English history in the Middle Ages using LEGO blocks. Contributors who pay more than $8 also receive six more books, including "Forbidden LEGO" a more free-style building guide that one reviewer called "The Anarchist Cookbook of the nursery," as well as "The Cult of LEGO", a tour of the block-building community. And for a $15 donation, contributors receive six more ebooks -- bringing the total to 16 -- including The LEGO Christmas Ornaments Book and Steampunk LEGO.
