Im messing with a way to make things glow. This is done in GIMP and isnt all that difficult.

I can do any color too, but of course i chose green (i have an obsession with anything green o.o )

As a side note, i can also make these into icons if anyone wants one, i have Feline and Canine (although the difference is minimal) Totally free of course with your name and color of your choice. And any other details you would like.
