"Man made by a fan of mothership glass" reading comprehension OP. Pretty sure they'll ship to the UK and with the advent of the Internet the world got a whole lot smaller. It's the only place I can find those glyphs and if you remove those from the circle it is identical to the mothership glass logo.

The fact is the majority of crop formations are man made. Find me where those symbols appear that isn't connected to mothership glass and I'll resume researching them and any possible meaning to the formation.
