Corona SDK for iPhone

Ansca company (founded by formers Adobe mobile engineers !) presents Corona, a development environment for iPhone that uses a proprietary SDK based on Lua language (scripting language widely used for games), a compiler (requires an Intel mac) and a simulator (that also works on PowerPC).

Among SDK’s features we note an OpenGL ES accelerated graphics engine, video support, as well as accelerometer, touch and camera support. A command-line debugger is provided. Multiple platofms support is planned. The compiler produces very small binaries..

A 30 days trial is available.
The full version (99$) includes a one-year membership to the Corona Developer Program, that allows to deploy to AppStore, and provides free SDK updates. It is stated however that compiling requires membership, so it may have to be renewed each year.
