 intro: I created the bamboo illustration in 2006 for my Martial Arts website using Adobe Illustrator and the gradient grid tool. 2015 I decided to use my bamboo as SVG on my website. Unfortunately, the gradient tool is not supported in SVG and I needed to recreate my bamboo with linear, radial, and other supported gradients in Affinity.

 intro: I wrote this book in 2017 out of the essays I’ve written on my Martial Arts website in the last 20 years. It’s a book in German about the Ninja and their secret art of Ninjutsu. I also designed the book cover for my book. The book was written with GitBook and can be read or downloaded for free as PDF, ePub, or Mobi eBook.
