Before I started writing this, I’ve browsed our #Lego collection for fun. It has dozens of interesting posts, some of them even I completely forgot about. What I’ve noticed is that most of the themes repeat themselves, specially impossible triangles (I think there is no need to post any more triangles for some time now). Anyhow, I’ve collected rest of the unpublished Lego illusions, and decided to close the trend. First one is obviously most complex, but I have some doubts whether photoshop has been used. Rest of the collection should be free of digital manipulation, but fortunately I have you to judge. Can you guess how each of them was built?
