Just don't ask that… the answer is always yes. Most of the things you can come up with is probably possible to do, it's just a matter of time, money and quality of the end result. Back to your question, can you elaborate it a little? Where would you like the beacon to spawn? What are you actually trying to do?
I want a beacon beam to spawn at the server spawn point, and I just want a beam to make the spawn look a little bit nicer.
