Mozilla's Webmaker takes the idea of Maker Space and puts it on the web. Each online project offers a split screen with the html code of the left and the preview on the right. Sort of like using Dream Weaver. The html also has tips written in. Very cool concept.
I love the way the Webmaker sets these up because you need for these projects is high-speed internet access, very basic sense of html code, and for these two templates membership in an online photo sharing service, such as Instagram or Flickr, and have patience.
It seems like a great way to offer make what would seem complex code to the un-techy easy to do. I thought what a fun way to introduce html coding to teens and tweens.
