Check out Felton's other site - daytum.com. It's an app and website that helps people get started, though the fancy visualizations aren't modularized just yet.

And http://www.reporter-app.com, an iOS app, also by Felton.

BTW, anyone knows why it is Nicholas Felton and feltron.com? (with and without "r")?

His friends gave him the nickname "Feltron"

'Tron' as a suffix suggests electronic or mechanized.
