|mobile 2 (tesseract)
This project is very much generated by mobile 1 but, also a strong backward
inspiration /stimulation/ came with tesseract through the science fiction
story "And He Built a Crooked House" by Robert Heinlein (I read
many years ago).
Mathematically inclined architect named Quintus Teal in the fiction, has
a brilliant idea to build house shaped like the unfolded net of tesseract,
to build a four dimensional structure. This project , mobile 2 is the most
of myself to design in 3D "to be 4D house". Assuming all possible
rotation in 10 positions of each of 8 elements, all together, there is
a quite number possible ("4D") arangements.
