According to its creator, Amar Sagoo, Tofu is a "different" kind of OS X application. It wraps text into limited-width columns to make on-screen text more readable.
After selecting a file, Tofu reads it in and creates a series of columns that scroll to the right, rather than up and down as in a traditional text editor or Web browser. It feels very much like reading a book. If you find on-screen reading tiring, Tofu may be worth a look-see. (Free, OS X 10.2 or later).
