(I was ontop of em) then I started whacking him on the head and he freaked out and shot me, sending me off into the white screened-no where-whatever land. I also filmed the whole thing 
You can also get in the triangle without someone in it so that you're standing up....Then press the space bar continuously and it looks like a ST (seisure thing). I have a hella lotta more new stunts but I don't wanna spoil them 
Oh I kinda forgot to say how this works....Well, basically, just jump over to the other ledge in the ceiling then jump over to the triangle.
