This is a basic Splash Screen I created using Gtk

{{{

@args -pkg:gtk-sharp-2.0

use System
use Gtk

class Splash inherits Window
	cue init

		.decorated = false
		.hasFocus = false
		.hasFrame = false
		.keepAbove = true
		.modal = false
		.skipPagerHint = true
		.skipTaskbarHint = true
		.typeHint = Gdk.WindowTypeHint.Splashscreen
		.add(Image("logo.png"))
		.showAll


class MainWindow inherits Window
    cue init
        base.init("My Main")
        #simulate something that times time like Thread.sleep(5)

    def main is shared has STAThread
        Application.init
        spl = Splash()
        while Application.eventsPending
        Application.runIteration
        MainWindow() #This is the window that takes a lot of time to load
        spl.destroy
        Application.run
