Dia dhuit,
Just wanted to let everyone using Windows 7 know that Microsoft has an Irish Theme / Desktop Background (2 separate downloads) available. You can install the whole theme, or just desktop background . It features a beautiful scene of the Beaghmore Stone Circles.
It is listed under Themes/International/UK and for just desktop background, it is listed under the tab for Desktop backgrounds/ Beaghmore Stone Circles (N. Ireland, U.K.)...Arragh!!!!!
