This project is built on top of the Helvetireader userscript created by John Hicks which styles Google Reader to make feeds more readable.
Flavored Helvetireader further styles Reader to make RSS even more fun to read and reduces the clutter to a minimum.
Flavored Helvetireader is available as a Chrome extension. Get it from here.
Fork it and let your imagination run wild!
The dark theme is inspired from Readability's Inverse.
