What Russian artist Nikolai Aldunin does is rather a very rare type of art. It’s an art that’s so delicate and precise he needs to slow down his heartbeats and know when is his next beat. Because every heartbeat disrupts his procedure.
Since he deals with making art so tiny it’s literally only seen by a microscope. His heartbeats shake his hand and this might damage what he is working on. We don’t notice our body movement when we have a heartbeat because it’s so small it’s unnoticeable. But when it comes to making items this small, it very much is.
Nikolai Aldunin makes extremely tiny golden items on already small items like needles or matches. The golden war tank you see below is standing on a sliced apple seed. The amount of detail on that tank is just staggering.[Source]
