This was a talk that I did for the ADUG Winter Symposium (4-Aug-2016) in Sydney. In it I build a cross-platform (Windows/Android) application for calculating fractals. It's on fractals, code optimizations and parallel programming. The images and details about the super-computers is from Wikipedia and the fractal zoom animation in the beginning is https://youtu.be/a26UXXVQAHg. Watch this presentation on YouTube, it's 85 minutes long - so grab some popcorn. I'll make the source code available shortly. You can alternatively watch the Melbourne version of this talk that repeated the following day (5-Aug-2016).
