Nobody named theirs Deuteron? (Sorry could not resist)
I seriously considered this name for a triton related project. Well there’s helion (metas autotuning dsl) at least.
Let's not forget the now defunct line of Trident graphics cards, dating back to the early 90s. Phonetically I thought they were talking about a driver for it.
Or Trident, which was (and maybe still is?) Joyent's flagship product in the private cloud space.
