Barcelona-based graphic design studio LoSiento has been exploring 'four dimensional' lettering for at least a year now, honing their craft alongside client projects. As in the iconic cover of Douglas Hofstadter's Gödel, Escher, Bach, the 3D object is an ambigram—i.e. it reads from multiple perspectives.


Of course, no one said it was easy: check out the video below:

Why is it called 4D, it's complex 3D, but 3D!
4D? Isn't the fourth dimension time or something? I should refer to my Buckaroo Banzai DVD for clarification. This is only 3D
There is no 'U' what gives?
emm It is in four dimensions because the character can be perceived from 4 angles onto the 4 faces.
four dimensions in this case seems to be a general term rather than a specific term.
however it can also be another explanation.
if you look at ambigram they are physically 3D but it can be 3 dimensions its height and width of a character and the same image from the inverted dimension.
Similarly, this typography can be viewed at 1 side (width and height), the reverse side, and their intermediate sides/phase. hence graphical 4D?
But I'll say it is just a fancy playing with words. Maybe they think If it makes graphical sense and why not market it that way?
