Frex – with zoom

After a lot of refactoring, Frex now has a code base that I can understand the next day. I took the opportunity to install version control on my laptop to save me from any potential “oh f%*k” moments, or at least make them not as bad. I chose subversion for this, and as the repository is located in my dropbox folder, I’m not worried about having to back it up.

I created a list of features I wanted this thing to have, and along with some speed and user interface improvements, the big feature I added for this version was zoom. This is a screenshot of the app running on my phone, showing a zoomed-in portion of the Mandelbrot set:

A little bit of Android coding

Back in high school, a friend gave me his book on fractals (thanks Damo!), and I spent hours and hours generating fractals using the bundled ‘fractint’ software. It didn’t matter that I was using a hand-me-down AT PC (everything was ok though, as this was the 8 MHz version!), watching the fractal generate line-by-line was fine by me.

Today I found the time and ambition to create for the Android platform a program that generates the Mandelbrot fractal. That’s all this program does (for now). It does it very slowly, with absolutely no bells and whistles. Say hi to “Frex” (“FRactal EXplorer”).
