Offering new logo

[thundergolfer]

Hey Dan,

Firstly, cool stuff. I've been curious about this kind of thing myself since learning more about Bazel. I saw the project logo and it sparked a desire to jump back into Adobe Illustrator for the first time in a while and develop on the concept.

Here's a pic of what I came up with quickly. A little rough around the edges but gets the point across:

An isomorphic view like Bazel's logo, but of the Tensorflow shape with Bazel shape embedded. If you like it enough I can make a PR replacing the current .png.

Cheers.
