Free Bootstrap theme resembling Material Design.
Bootswatch offers Sass and Less files, so the theme can easily be integrated into your usual Rails application.
Implements only Bootstrap features which means that some Material stuff is missing, but also that you can easily use or replace the theme.
Does not come with extra JavaScript; some effects like button click ripples are implemented via CSS.
Also check out their other themes which can be used in a similar fashion.
