Scratch for Holiday for Chrome
More About Scratch for Holiday
Scratch 2.0 introduced the capability for Extension helper apps. These extensions allow Scratch to communicate with other devices, so that they can be controlled within Scratch programs.
Scratch for Holiday is a Scratch extension helper app that connects Scratch to Holiday by MooresCloud (http://holiday.moorescloud.com). Launch the app, then launch Scratch, and Scratch will be able to control Holiday!
We think this is a wonderful - and very visual - way to get kids into programming.
