Something completly real?
Getting closer ....
LukeFF found a pic of an SV PPI scope. So far, it's the best we've got ....
Compare to this PPI I slapped together :
The grid could be brighter ... could be cleaner ... but it has that faded, coffee laiden, finger print rub kinda look ... eh? By the way, the sweep/contacts/text are @ 80% using a slightly brighter green background effect.
EDIT : I have a variant with azimuth ###.
Suggestions?
EDIT : I have one .... marks like this ">" and "<" at 30 degree increments. Bigger "{" @ 0,90,180,270.
