Beam Particle Tutorial

I came across this wonderful tutorial called “Beam Particle (Tutorial)” on the wiki section. As the author admits he has skipped showing in detail a lot of steps for brevity and I respect that. I was wondering if anyone knows of a detailed version of that similar amazing effect he creates. It really is awesome. I am still having trouble filling in the gaps since its been a few weeks since I switched from Unity and I’m still on the steep part of the learning curve! Thanks!
