Snap extensions

One of the good things op Scratch being open source is that it encourages the development of variants. Quite a famous one is Snap! and when you join the conference you can meet the complete Snap! team in person, chat, play and code with them. And as they live on diiferent sides of our planet that's a very special extra to the allready amazing Scratch Connecting Worlds conference. 

Both Scratch and Snap have ignited hardware extensions for sensing and controlling the outside world. Competion at its best :-)
