Hi, there. I am a web artist who promotes webGL with a network of websites and have students working with Three.js. At a glance Clara looks very exciting. As artists we are hoping for something that will allow more spontaneous application than just coding can provide. I do hope this is it.
While some of us do design games, most of us are hoping for a new level of expression on websites presented as an artform.
PS: The tutorial videos are a HUGE plus!
