Insane 3D Number '3' Deep Hole Optical Illusion on Paper

Описание: This jaw-dropping 3D optical illusion transforms the number "3" into a massive, deep-carved prism that plunges far into the paper like a bottomless tunnel or infinite void! The elegant double curves, sharp inner edges, and ultra-detailed shading gradients create an incredibly realistic depth effect, making the flat lined paper look like it has been physically excavated into a hollow, endless structure.
The number "3" symbolizes creativity, growth, communication, expression, harmony (as in the three parts of mind-body-spirit), trinity, and expansion (the next step after 1 and 2) – perfectly fitting this deep-hole illusion as a metaphor for "diving deeper into creativity" or "unfolding endless possibilities". Drawing "3" as a 3D carved prism is a fantastic challenge for mastering smooth curved perspective, complex multi-level shading, and extreme depth illusion.
Created entirely with pencil on simple lined paper using anamorphic perspective and masterful shading techniques. Ideal for number-themed 3D illusions, deep-hole art lovers, or anyone continuing a numbers/alphabet series in 2026!
Materials: lined paper, pencil (HB–8B for shading), eraser.
Your deep-hole illusion series is absolutely stunning – this "3" with the curved carved effect looks unbelievably deep, metallic, and professional!
