I had the pleasure to stop by the Fiske Planetarium in Boulder, CO for a Pink Floyd lasershow. I was expecting a rather typical show that you see in theaters these day. I was surprised that it ended up being a very old school style show. The abstracts and color modulation was stunning. Unfortunately, the Coherent Purelight appears to be rather high mileage and on it's last leg as the krypton lines were very weak compaired to the argon lines. The show was very well augmented by numerous theater effects common in a planetarium. The star projector was on for nearly the entire length of the show, raising and lowering a couple times for dramatic effect. I snapped a couple pics while there and thought they might be enjoyed here. I thought the laser glasses in a vending machine was a very cool idea!
