Aaron Amatnieks, aka Flickr user akama1_lego, built a Lego dragon that breathes real fire! A tricky proposition when your medium is a polystyrene copolymer that melts at a temperature below the boiling point of water. A butane lighter has been fully incorporated into the structure, including a mechanical start-lever disguised as a rocky crag on the back side of the mountain.

Aaron has also created a Lego diorama that incorporates moving water. I have not included a picture here because, well, let’s just say it’s a bit risqué. [via The Brothers Brick]
