I've done a lot of work on the app this weekend to get it working nicely with the new iPhone 5 and still work with the iPhone 4 and 4S.
Things have gone very well and I think I can safely say that it is working exactly as I imagined it at conception!
Lots of scribbling, drawing, number crunching and head scratching to get there though.
Seeing as I am so pleased with the result I wanted to share it with you. So here are a few screenshots showing the new predefined patterns working.
