This is a 2D animation I did more than a year ago for a bio-science society - C3BS : http://www.c3bs.com/en . It is meant to introduce a new kind of needle to inject product inside the heart.
I did it in Illustrator and animated it in AfterEffect. I needed to find a way to get this perfectly smooth animation and render, which illustrator proved helpful for.
