Because magmak insisted.
Here, you can have any sig you want. Give me a topic, any text you want, a theme, and any specific details you want. I can do either vector graphics or traditional Photoshop-esque styles. Here are some styles I'm good at:
Grunge: Just look at my sig for an idea of what this means. You can have either colorful or muted tones, whichever you want.
Line Art: This takes a little more effort, but the results are good. I'm a lot better at cartoons than realism, though.
Transmogrification: I can put your/your dog's/a velociraptor's head onto something and make it look realistic. I could also do, say, a Pegasus, or a dragon, but that would be a lot more complicated.
Logo-style art: A bit like line art but a little more logoish and less cartoonish.
The one thing I can't do is animation, and besides, most animated sigs are really annoying anyway
