The proliferation of nostalgia-inducing Lego sets indicates that they're far more than just a child's toy. The Danish company is taking this to heart with their latest release. Named Forma, the new line of models are meant specifically for adults. Based on the Technic building system, the first model consists of 294 elements and represents a fish that moves as you turn the crank at the bottom. Customizable foil sheets form the animal's "skin", giving it a more realistic form than would normally be possible with static bricks. If successful, the campaign will likely lead to further releases of artistic interpretations of plants and animals.
