In this case I am thinking a symbol probably mainly recognized by the Republic and the clone armies. A friend of mine said is looks too engineer like, so I am going to give it a shot without the middle details to make it more basic like you said, get rid of the spikey swirls and tilt the design 45 degrees and see how it looks...
OK, going to change the title of the thread...
How about we as a community come up with a medical symbol for use for Republic, Empire, Alliance, etc...
How about it? We all could submit ideas and vote on a generalized symbol.
Think about it this way, if there was a wide spread use of a symbol agreed upon, when someone made a custom of say a medic, or engineer, or janitor, etc... they could throw a symbol onto their custom and there would be no doubt of what the custom was of!
Another thing to think about. The 501st eventually became Star Wars canon and it just started out as a bunch of fans who dressed up as stormtroopers. With enough wide spread use of a symbol though the customizing community might eventualy catch on to other things, like the star wars rpg, star wars galaxies, maybe even the comics and who know...maybe in one of the planned star wars television projects. I am not saying that for certain it will, but wouldnt it be worth giving it a shot?
So my idea is lets as a community come up with some ideas for some symbols for different groups:
Organizations: (for example...)
Occupations to have a generalized symbol for...
Medical (Medic, first aid, hospital symbols)
(just a few examples...)
These would not be universal, but significant for a specific Government type.
So lets start making our mark in the Star Wars Expanded Universe!!!
