Agreed. Having that option is an absolute must. I've been a programmer for 20 years so I think this is a step in the right direction. The point I was trying to make is that in the last few years, there's been a lot of talk about getting kids interested in programming but there's a lot more to the sciences than just programming. We need to make general math and sciences more interesting to kids. Maybe programming will be that catalyst to leads kids to a love of math and sciences.
It's a good start but I think it better to focus on getting kids interesting in general math and sciences (of which computer science is a part). The next generation of entrepreneurs need to focus on solving bigger problems and not just focused on making apps. Of course all of it depends on how we can get kids more engaged and interested in learning (whatever subject that moves them).
Yes, the landing page and sign up process are a work in progress at the moment. The client app was built using GWT (Google Web Toolkit) but with significant custom development. The backend is Java/MongoDB/AWS and some other services.
The page itself isn't yet optimized for mobile. That's coming soon. If you view the video in full screen mode, it's a lot clearer. There'll be an option to select the color scheme in a future release.
