Hi! I’m Jon. I do a bunch of different stuff.

Secret Lab

Secret Lab is a game dev studio based in Hobart, Australia. Paris Buttfield-Addison and I have been running the joint since 2008. Practically everything you see on this page was done through the company.

In-Person Training

We frequently run iOS developer training, which have been pretty well received by attendees!

Also! Our next training will be held in Melbourne, on 25-27 August.

Open Source Software

  • Yarn Spinner
    • Yarn Spinner is a tool for creating interactive dialogue.



I’m a frequent author for O’Reilly Media, where I’ve written a number of technical books. I mostly write about mobile app development, but I’m also known to write about video games. I usually write with my colleagues, Paris Buttfield-Addison and Tim Nugent.

Video Training

I’ve recorded a number of video training series for O’Reilly, along with my regular co-authors, Paris Buttfield-Addison and Tim Nugent.

Several of our courses are available as Learning Paths, available exclusively on O’Reilly’s Safari Books Online service.
