Same 'gloss' , many 'signs'...

[Tim Grove]

I've noticed in looking through the signs in Sign Puddle that there are 
many signs which have the same gloss, but are represented in different 
ways. Looking at the ASL dictionary, for example, the gloss 'about' is 
associated with 5 different SignWriting images. What is the origin of 
these different versions? Do they represent different dialects, or are 
they simply a matter of personal choice? I would appreciate any insight 
which you anyone could give. Thanks!

Best regards,
Tim
