The original idea I had for this was to have it flash on and off so it would look like something from Dr. Frankenstein's lab (to see this, you'll have to look at it in "original" size). Unfortunately, it was way too big to get a decent looking animation in a graphic of the small size I needed for a web title so I went with the simpler non-animated version.

I tried keeping the red glow in the still version, but the gradient continued to make the file size too big to use so I finally just went with dripping goo on a plain black background.
