Anyone have a cool wood breaking "technique" for karate?

When I say technique I really mean like combination. Of course there is tornado kicking, knees and roundhouses, but those are too easy. I did a demonstration with those yesterday.

I have a demo in a few days, so I'm looking for an awesome combination.
For example, round, then tornado... Or crescent, then jump crescent. Etc.. IN A ROW...

Thanks!
