It's MUCH more fun if you use base -2i.

Just do -i*(same stuff as before) and you're done.

I don't understand the two previous posts.
airship, would you please demonstrate how to count 1-10 in "base -2i"?
Psy-Kosh, would you please demonstrate the same?

No, wait, I was wrong. Multiplying by -i won't do it.
Lessee... hrm, not sure how to do it in base -2i, actually. Would need to think about it somemore.

The places are all powers of -2i instead of -2 as suggested above, or simply 2 in regular old binary. So these are the first six places in binary:
64 32 8 4 2 1
Here they are in base -2:
64 -32 18 -8 4 -2 1
I is the 'imaginary number', the square root of -1. Powers 2i and -2i are kind of hard to get your brain around at first, but are really no different to work with than the other binary bases, other than the fact that they involve imaginary numbers.
Here are the first six places in base 2i:
32i 16 -8i -4 2i 1
And in base -2i:
-32i 16 8i -4 -2i 1
I figured this three times and I'm still afraid someone's going to jump in here and correct me! That'll teach me to make smart-alec remarks!

Man, did I mess that up when I typed it in! LOL!
The numbers are always:
32 16 8 4 2 1
It's just the signs and 'i' associations that change.

Thanks for catching that error regarding base two counting, Airship. I was about to let you know that you forgot the 16.
