One is 'sverchok', the other which may soon become part of Blender core is 'Animation Nodes.' Jimmy Gunawan of Blendersushi goes into fantastic detail about these two on his youtube channel if you're interested.
Oh and the best designed item I own? Swiss Tech Utilikey. A key shaped multitool with such a satisfying opening action. I use mine every day.
Others. - the scissors on the tiny swiss army knife. BEST nail scissors ever.
- Freeplane . Mind mapping software that I find new uses for on every project. So many export options too.

Smaller and not quite as aerodynamic, but nevertheless it was shipped, and widely used as taxis which proves its versatility.
Not sure why, but I just love the teardrop concept. No matter how flat and squared the front of the vehicle, add a taper to the rear and all's well with airflow.
