I think I updated the article with a reference to skew binary just a few seconds before your comment ticked in. Yes, it is an existing number system with the (sole) interesting property, that increment and decrement is very simple to implement (that sounds almost poetic).

But that does not IMO justify using it for anything other than slides for a CS lecture :)

Actually, it is called Skew Binary and it does have some useful properties for computer science: http://www.cl.cam.ac.uk/teaching/2004/IntroFuncProg/lecture08.html

I take it you incremented what page you were on a lot?
