Yea. They have a canvas wrapper that this guy did not use so you don't have to do that. With that being said, this project https://github.com/rubys/ruby2js https://github.com/rubys/ruby2js is more appealing to me. Sure it doesn't pass more RubySpec tests than Rubinius like Opal does, but it works. The Angular interoperability is especially appealing to me. It also generates readable javascript.
