I’ve been a fan of Lua since the early 2000s when a friend introduced it to me, even though I never got around to finding the time to properly learn and use it in production stuff. We have discussed about using Lua as a scripting language to allow for downloadable bundles that would extend AthensBook/ThessBook functionality (or fix bugs, or provide dynamically determined personalised features etc., but that never happened until now, due to licensing restrictions by Apple) for ages. Codify is an unbelievably cool app that leverages lua to provide a simple programming environment for the iPad. Combined with the general appeal of the device, the lack of third party, scripting programming environments for it, the ease of programming and use of Codify and the excitement of using such great hardware, I feel that Codify might be the Logo/Basic equivalent for this generation of children between the ages of 5-10, a great introductory platform for programming and an amazing tool for everyone else. And at $7.99 I think it’s a steal. You might want to use a bluetooth keyboard for it though; typing code on the on-screen keyboard seems like a horrible horrible nuisance.
