RunRev LiveCode

RunRev didn´t have a booth at Macworld expo, but hosted a get together for their users in a bar two blocks south of the Moscone center. Much more important: you can use their LiveCode, which started as a Hypercard clone on various UNIX systems, to develop software for Mac, iOS and Android in a way that ordinary users can use it to develop their own software. Highly recommended! Licenses start at less than 100$.
