HyperCard was ground breaking in its day for sure. I'm the CEO of LiveCode. We're an open source, modernized platform that lets you build apps for all popular platforms and devices. We still retain the best ideas from the original HyperCard. We have a vibrant active community with many successful apps developed. We also created one of the top100 Kickstarter campaigns of all time last year, to build a next generation version of the platform! Check us out at livecode.com.
