My pre­vi­ous post ex­plained how to cache whole web pages as im­ages. Now see it in ac­tion. This is a light­weight RSS read­er, op­ti­mized for com­ic books (but it works for any feed) and for off­line use (but it works on­line too, of course).

Not ready for pub­lic use yet, but if you look around you can find the code some­where ;-)
