Is anyone besides William Bricken doing any computer work with the Laws of Form by G. Spencer-Brown. This book is not too hard to follow, but understanding what you have got is another matter entirely. This is the arithmetic of indications said to underlie (and extend) things like Boolean algebra. It claims to rehabilitate (or perhaps, just to habilitate) a notion of imaginary truth values analogous to imaginary numbers. Any info/hints/flames welcome.
