Artists love to depict unique and creative ideas in digital format which cannot exactly be created in the real world. Some machines and concepts are so complex, they do not make sense to be created here. But that doesn’t stop creativity from mounting at all opportunities!
I have gone through some infamous Dribbble shots and constructed a showcase full of machines. These are illustrated, 3D-rendered, sketched, vector-rasterized, and tons of other artistic formats. Be sure to peruse this collection and soak up any cool ideas for other alternate illustrations.
