"ScratchJr is a tablet-based coding environment for kids 5-7. It's based on Scratch, the wildly popular Open Source kids' coding system. This Kickstarter project has currently reached its goal for an iOS release, but they have a stretch goal of $60K to develop a version for Android tablets. My 8-year-old loves the main Scratch program (http://scratch.mit.edu/) and I'd love for my 5-year-old to have an even earlier introduction to programming." - Evan Prodromou
