From a LinkedIn post earlier today I found out about a working Rubik’s cube built by South African developer Zukisani Zamela with HTML5 and THREE.js (possibly inspired by the cube seen in this tutuorial). Try it out here.
While it needs some refinement it does work and is a good example of the growing power of browsers . . . and developer ingenuity . . . today. Ernő Rubik would be proud.
