Task
Show off your best scientific illustration !
The main purpose of this question is to share beautiful scientific pictures, preferably with an educational aspect.
Content
Your post must contain a nice picture and the associated code. One can post several pictures, but it must be done in different replies. Of course, it must be done with LaTeX & Friends : the post must start with a short sentence to present the language that you chose (TikZ, Asymptote …) and the main packages that helped you to make the picture. Don't hesitate to add comments.
Reward
The satisfaction to share without expecting a reward 🙂
Ok … 300 points reputation bounty for the best up-voted post until the 15th of Feb.

The following image illustrates the blowup of a plane at a point--an important construction in algebraic geometry (compare the cover of this book). The image was produced using Asymptote. (Note: the code and the image have both been refined since they were first posted.)
