The two pages are:
(Tom, do you have a better suggestion for titles?)
The first investigates rotations of the hypercube, and the second, slices of the hypercube. I have tried to make them fit in with the current artwork in terms of layout and coloration, so I hope that you feel they work well with the exiting pieces.
I also include artists comments and mathematical discussion as we do in all the other pages. In addition, I have generated about a dozen MPEG movies as support materials, but I have not had time to write the comments for them yet. I'll do that as soon as I can.
Finally, I have drafted the explanation that you (José) asked for to be used in the printed materials. It is about 4 pages long, as you requested (in TeX format) though it may be more than you wanted. If so, I have several places in mind where it could be cut. Let me know, and I'll send you a shorter version if you want.
If you are satisfied with the images for the additional panels, I'll send the files to Mr. Esteves. Please let me know what you think.
