The first physically implemented 4D cube.
HATO consists of a 222 cube and 6 smaller embedded 222 cubes therein. Embed is a term in mathematics, we think it is also a suitable description of this structure. Compared with software simulated 4d cubes(2^4 cube), the total number of positions of HATO is significantly larger.
The planned launch of this product was stopped by a recent Typhoon named HATO and subsequent blackout for a whole week. In order to mark this event, the inventor took the name of HATO for this project. Patterns on the sphere was added after this event and was inspired by Typhoon sign and Auspicious Clouds.
In January 2018 two different transparent versions of this puzzle hit the market. One with coloured balls, one with stickers.
