Tensor Altar
Touch the shadow of a 4D thing until it admits which room is real.
GYROSCOPE / TOUCH / TESSERACT
Find rooms in the folded object.
This is not a physics simulation. It is a little machine for poking at a 4D cube's shadow. Tilt your phone to rotate the higher-dimensional camera. Drag to rotate the visible shadow. Pinch, mouse wheel, or press auto-unfold to open the tesseract into something uglier and more legible.
- Gold node = current room to find.
- Pink slice line = your current W-plane cross-section.
- Green skeleton = projected tesseract edges.
- Tap/click the gold room when you think you have it.
What the rules mean
A tesseract has sixteen corners. The game names each corner as a room using four signs, like +-++. You are not solving math homework; you are rotating a shadow, slicing it along W, and unfolding it until the named room feels obvious enough to touch.
