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.
