Can sp-hybridized (i.e. triple bonded) carbons conjugate?

This is specifically with regards to figuring out if something is aromatic. I couldn't find anything regarding this, but I figured there must be something blatantly obvious that I'm overlooking for this to not even be a common question.
Thanks

Yes. You get what are called cumulenic resonance structures, the name deriving from cumulene.

Because of bond alternation, often the various resonance structures are no equivalent in energy, however.
