We are huge fans of puzzles in all forms. It could be a cool old wooden puzzle or the engineering challenge to make something work visually in which it looks as if alchemy and wizardry are at play. Take a look at these two puzzles and or sculptures and look at how they were made. Any great fabricator has tricks up their sleeve to fool the eye. If ya have any other tips or cool homemade work, send them along or post up a link.
