(November 19) marks the 40th anniversary of the musical concert set to laser lights known as Laserium, once seen in many
planetaria worldwide, including Pittsburgh's original Buhl Planetarium
and Institute of Popular Science (a.k.a. Buhl Science Center). As Laserium is considered the first
on-going laser show that was not part of a special or one-time event, it
is also thought that Laserium launched the international laser display
industry.</span></span></div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: HelveticaNeue,Helvetica Neue,Helvetica,Arial,Lucida Grande,sans-serif; background-color: transparent; font-style: normal;"><br><span style="font-family: inherit;"><span style="font-size: 13px;"></span></span></div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: HelveticaNeue,Helvetica Neue,Helvetica,Arial,Lucida Grande,sans-serif; background-color: transparent; font-style: normal;"><br><a href="http://spacewatchtower.blogspot.com/2013/11/laserium-40th-anniversary.html">http://spacewatchtower.blogspot.com/2013/11/laserium-40th-anniversary.html</a></div><div> </div><div>gaw</div><div><br>Glenn A.
