These are all screenshots of GtkFB running on matroxfb in 800x600 16 bit.
The testgtk program distributed with Gtk+ with a few windows open. Note the antialiased fonts and the asian, indic, russian and hebrew scripts.

Another test program, showing the powerful rich-text editor in Gtk+. Note the right-to-left arabic text parts.

This is just a screenshot of a tetris program i found on the net and compiled with GtkFB.

Here is the Dia diagram editor in full action on the framebuffer. I had to make a few small adjustments to make dia compile with Gtk+ 2.0, something which took me about 30 minutes. The antialiased view on the lower left is rended with the libart library, which can be found in the gnome cvs tree.
