I'm having real trouble visualizing how Buchholz hydras work. How would you represent, say, the ordinal ζ₀ as a Buchholz hydra? A hydra that represents ε₀ would also be appriciated.

(At first I naively thought that the single-branch tree 0-0-1 would be ε₀, but when I expanded it in accordance to the rules, it didn't work at all)
