Eitan works on an algorithm for his Rubik's cube. After 24 hours straight, he is moving: "Well, it's really complicated because first, you have to know your Rubik's cube, and you have to understand the relationship between each piece. There are certain steps to cracking it. Gradually, over time, it gets closer. Pretty much it all involves understanding where to put each colour in relationship with all colours."
And, he adds, "there are 43 quintillion combinations."
