Ruby + iPAQ

I've built some small apps in Ruby, using WiSe for my iPAQ that dock into ion, the default window manager of the familiar linux distribution:

A menu app that uses files from /usr/lib/menu as already provided on familiar (and other debian(-based) systems),
A CPU meter (that munches noticable CPU on iPAQ: 1%),
A battery meter,
A clock,
A CPU speed switch that switches between 118 and 206 MHz (nice to press before suspending the unit),
more, but too alpha to link to :)
