I'm currently writing some sci-fi, where most of the time should be spent on a planet where is sand almost everywhere. You know, deserts, maybe some hills and thats it. It is because one sand artist will do for me the pictures and small videoclips, so if you can play PDF videos on ipad or something, you can see how this stuff happens. Also there'll be PDF just with pictures. Problem is that I don't know if I should start by describing of alien livestyle rightaway. I liked one book from Arthur C Clarke that started by description of some primitive culture, but that may be because I'm kind of geek.
