Ninja Pixel needs a logo

This is what ninja pixel was looking for in their logo design

I blog and tweet about visualisations (drawing graphs, basically) and want a logo to compliment my domain and twitter handle (www.ninjaPixel.io, @ninjaPixel). The design must incorporate something to do with a ninja, and possibly something to do with visualisations.

I like the idea of a blocky, 8-bit ninja character (see attached image, lifted from a google search, for what I am inspired by). I'm not wedded to this idea though, if someone has a better suggestion.

The colors I use on my site are listed in this google doc, feel free to use them / ignore them! https://docs.google.com/document/d/1OLFow3SQoN6Rwc0eWPt_EPAKy3tLvUcse9PsJKGW5dc/edit?usp=sharing
