Logo

Prototype 1:
"J" of "Jupyter" created in the negative space of planet and moons. Could stand alone as logo, as well as have type alongside it. 

Prototype 2: 
Similarly with prototype 1, the J is revealed in the planet but doesn't include moons. 

Prototype 3:
More abstract representation of jupiter and its moons. Clean and simple logo with san serif "Jupyter" (still deciding which font to use). The type can easily be separated from the planet and used on its own.

Prototype 4: 
A very abstract representation of planet jupiter. Based on the idea that IPython (Jupyter) is a place where multiple people come together and contribute, the shape is created by multiple pieces coming together. Through the use of color, the shape would have an almost 3D shape and feel to it. 

Prototype 5:
Again, based off the idea of multiple ideas and parts contributing to a single piece, this logo would show different layers pulling back and revealing the "J" in "Jupyter".

Prototype 6: 
Pretty self explanatory, but a unique font (maybe hand-drawn) would be used to created the name "Jupyter" with the planet being used as the dot. The two could also be used independently from each other. 

Prototype 7:
Based off of drawings of jupiter from Galileo. Super minimalistic and clean, but both pieces could work beautifully apart from each other.
