there are 15 or so high powered spot lights along roofs on oconnel st dublin.
goto the website and use their applet to position the lights & make patterns with their beams.
the actual lights on the st cycle through all entered patterns.
the site gives you an eta on you pattern being displayed, and pics are taken of your pattern, and a small web page is put up of your design afterwards.
their is also a live feed from the webpage from 4 cameras positions around dublin watching the spot lights.
pity you can’t see the beams in the actual camera shots,
the pics on the left are the java applet in which you place the beams.
went down last night to have a look – got photos of my own – not just the automatically generated ones.
