I recently designed a Twitter header in Adobe Illustrator, it has kind of a them to it. Teeth, yes, scary I know. Stop crawling under your beds and read the rest of this post. If you need something to scary away the peasants of Twitter away this is perfect way to stylize your profile. Strategically and carefully designed will the grace of the pen tool.
As you can see it is quite marvelous which is why you see my store page for more designs. I have some freebies as well. Money will go to a good cause for me to make more stuff and it's pay what you want.
