CubeSolver 3D · live

Scramble it, then play it backwards.

This cube turns its layers with the same face-turn table CubeSolver 3D uses. It scrambles itself, then plays the inverse sequence back to solved: the “scramble + inverse = solved” identity the project's tests check. Drag it to rotate.

The Cost of Saying Less (opens on Medium in a new tab)

A few months ago, my friend texted me “We need to talk.” I spent three hours analyzing every word we had ever said to each other that week, trying to figure out where I had slipped up.
