Teeny solar engine fits in a wine glass

If you thought building a ship in a bottle was difficult, how about hand-crafting these micro-models of machines that are small enough to fit into a wine glass? They're the work of a man with nearly infinite patience named Szymon Klimek, whose created dozens of these tiny models — over a hundred in all.

He gets paper-thin sheets of brass and cuts out the parts he needs, then shapes them and glues them together by hand to create these exquisite engines. Check out the gallery below for the multitude of mini-machines this guy makes, and don't miss the video of his masterpiece: a working solar engine. Remarkable.
