Build your own singularity engine

[Nnystyxx]

See, that'd be fucking sweet. Launch particles at it to start the engine and feed gas and possibly some sorts of chems/other fuel to the result to make your own pet star of sorts. Then people could show off how big they got it and how much energy it produced (a factor of its size vs density/color/stability). Obviously, lack of containment could send it on fiery, surging wheels of destruction or, if intentionally overloaded, cause it to go nova. And if you collapse a really fucking powerful one, it becomes a singularity, just as it should be. It would be a combination of both into a thematically exciting thing and a hobby for the engineers to do, trying to make the best/coolest star engine.
