Diabetamatic Icon

Awhile back I posted a little web app I made, Diabetamatic:

The Icon I made was something that had zero thought (this was a coding exercise after all), and was pretty ugly. I got sick of looking at it on my home screen.

I decided to make something with a little more flair. If you can't tell the mark is of a syringe, since that is the core of what the app does.
