History of the Laserium

Joshua Bearman says: "Sadly, when the Griffith Observatory grandly re-opened last month, the laserium didn't reopen with it. That was the last spot you could get stoned and see krypton lasers accompanying Shine on You Crazy Diamond. It was also the first Laserium, I discovered -- the laser light show was created there, in 1973. I tracked down the creator, who still makes the projectors at his facility in Van Nuys. Turns out the Laserium is also part of a long line of synesthetic attempts to divine the common energy of light and music, from Thomas Wilfred to Scriabin back to Pythagoras. Who knew that Floyd at the Planetarium was just another facet of the Harmony of the Spheres?" Link
