I know I keep repeating this (both here and on my blog), and perhaps people are tired of hearing it, but there are 5 dots, not 4.
It looks more like this than any of the examples posted so far except that the VMS 5th dot looks like it's veering away, rather than creating a triangle (the resemblance to this is quite possibly coincidental, but I'll post it in case it might be relevant):
