Creating HTML5 widgets for Adobe Captivate 6/7
I decided to write this post due to the frustration and lack of information out there on how to make HTML5 widgets for Adobe Captivate. There is almost no documentation on this and the only useful article I could find was riddled with mistakes. My approach may not be the best but this should get…

Windows 8 start screen in HTML, CSS and Javascript
About 7 or 8 months ago I built a tile based launch page at work to launch learning modules which looked similar to the Windows 8 start screen. When I had spare time I kept building on and adding 3D animations to match it even closer to Windows 8. Then I kind of forgot about…

I was using the HTMLLoader class in Adobe AIR to load content and I came across an error where my Javascript was calling console.log(). In the AIR HTMLLoader environment this function does not exist so I…

A simple way to get native alerts with Adobe AIR
In an AIR project I am currently working on I wanted to have native alert boxes in my app rather than building custom pop up boxes. There is no built in way to get native alerts in AIR and I remembered reading this interview over at leebrimelow.com a while back where a developer at Illume used StageWebView…

I have just uploaded my new showreel to Vimeo. A couple weeks ago I was listening to TripleJ in the car and I heard this amazingly bizarre, vintage, sci-fi, horror metal song come on. Unfortunately I missed what it was called or who the artist was so I spent ages trying to figure it out.

Leveraging iOS hardware via the browser with Javascript
Just another quick post tonight. I have bigger one lined up for tomorrow I promise. I just wanted to show a little experiment I did a while back with JavaScript – accessing the Accelerometer and Compass data in Safari on the iPad. Below is a short video demonstrating it if you don’t have access to an…
