A common trait of technoludic online scenes and communities are the efforts undertaken to document, preserve and redistribute specific knowledge. The afols [adult fans of lego] have developed many building techniques beyond those found in official instructions. Back in 2007 Didier Enjary collected a lot of those in his ‘↓The Unofficial LEGO Advanced Building Techniques Guide‘ [.pdf | 1.7 MB]. Didier’s guide explains the geometry of LEGO bricks from scratch, then proceeds to particular techniques. All in all his guide is a testament to the afols’ intellectual and practical appropriation of the LEGO building system.
