Someone published a novel a while ago where each chapter only used words containing one of the five vowels. So, the first chapter consists of words containing a but not e, i, o or u; the second chapter consists of words containing e but not a, i, o or u, and so on.

Makes me wonder -- it should be possible to write a novel using only the letters on Colemak's home row. Any thoughts? Punctuation and spaces would, of course, be allowed.
