What you're seeing
Three worlds stacked like a ladder. A 1D being lives on a line and sees only points. A 2D being lives on a plane and sees only edges. We live in 3D and see only surfaces. Each world perceives higher-dimensional objects as lower-dimensional slices — not the full object, just the cross-section where it intersects their world.
How to read the graph
Toggle between God View (you see the full higher-dimensional object) and Resident View (you see only what someone inside that dimension perceives). The contrast is the whole lesson. Use Split View to see both at once. Press play to watch the object pass through, or pause and drag the scrubber to control the slice position manually.
The key lesson
A higher-dimensional object appears as lower-dimensional slices. A 1D being sees intervals. A 2D being sees cross-sections. We see 3D volumes. None of us see the actual object — only our dimension's intersection with it. This is not a metaphor. It is geometry.
