wxRuby has a Frame#show_full_screen method which will display a Frame 
(Window) across the whole screen area without any decorations such as a 
title bar. It should be possible to suppress task switching using event 
handling. It also has a Timer class.

wxRuby works with native widgets on Windows, OS X and Linux/GTK. It's 
straightforward to install (gem install wxruby); no messing around with 
extra .dlls or .sos or packages.

require 'wx'

Wx::App.run do
   frame = Wx::Frame.new(nil)
   frame.show_full_screen(true)
end
