Well, any symbol that consists of two crossed lines would to: + -> |
-, X -> / \, etc.

You could also do a circle and an X, with a circled X being the combination.

I haven't been following the two-bit ballot discussion too closely, so forgive me if this has been already discussed.  How is a two-bit ballot an improvement over having the voter rank the candidate on scale of 0-3?
