No, maybe size is limited but the inner surface of it is whatever we dump in.

I think there is some movie poster out with an "evolutionary transition" ape to man strip, but that would be too obvious a ripoff and even the idea has been used too many other times (stooping hairy body gradually stands upright etc.) By the way, this reminds me. I have an artsy little animation I wanted to put on one of the boards somewhere, but I can't because the storage site we have (where the rainbow book inmage is stored) for some reason won't accept it - maybe because animation is an .exe file and it's a free site and has some limits.

But: anyone who would like to see something brief and eye-enhancing, please write me at moderator@mdcplus.com and I will send it back to you as an attachment from my hard drive.
